OCTOBER BIRTHSTONES – TOURMALINE  have a wide variety of exciting colors with one of the widest color ranges of any gem. Tourmaline’s colors have many different causes. It’s generally agreed that traces of iron, and possibly titanium, induce green and blue colors. Manganese produces reds and pinks, and possibly yellows. Some pink and yellow tourmalines might owe their hues to color centers caused by radiation, which can be natural or laboratory-induced.
Mineral: Tourmaline;
Chemistry: Elbaite Na(Li1.5,Al1.5)Al6Si6O18(BO3)3(OH)4;
Dravite NaMg3Al6Si6O18(BO3)3(OH)4;

AUGUST BIRTHSTONES – SPINEL The Black Prince’s Ruby. The Timur Ruby. For centuries, spinel, the great imposter, masqueraded as ruby in Europe’s crown jewels. Until recently, spinel was an underappreciated gem with little consumer recognition. Increasing demand for ruby alternatives rekindled appreciation for spinel’s rich red color and history. In ancient times, southeast Asia’s mines yielded exceptional large spinel crystals, which became the treasured property of kings and emperors, often passing through many hands as spoils of war.
Mineral: spinel;
Chemistry: MgAl2O4;
Color: red, orange, pink, purple, blue, black;
Refractive index: 1.718;
Birefringence: None;
Specific gravity: 3.60;

COLOR: The most valued spinel colors are bright red, cobalt blue, and vivid pink and orange. Pale lavender is more affordable;
CLARITY: Spinel with no visible inclusions is preferred. The more prominent the inclusions, the less valuable the gem;
CUT: Spinel is most often cut in cushion and oval shapes. When properly proportioned it has excellent brilliance;
CARAT WEIGHT: Fine-color spinel is rare above five carats. Most fine-quality rough is cut to non-standard sizes to save weight;
AUGUST BIRTHSTONES – PERIDOT Found in lava, meteorites, and deep in the earth’s mantle, yellow-green peridot is the extreme gem. The ancient Egyptians mined peridot on the Red Sea island of Zabargad, the source for many large fine peridots in the world’s museums. The Egyptians called it the “gem of the sun.” Today this gem is still prized for its restful yellowish green hues and long history. Large strongly-colored, examples can be spectacular, and attractive smaller gems are available for jewelry at all price points.
Mineral: Olivine;
Chemistry: (MgFe)2SiO4;
Yellowish green;
Refractive index:
1.65 to 1.69;
0.035 to 0.038;

Most fine peridot is eye clean. Tiny black spots might be visible with magnification;
Peridot is cut in a wide variety of styles, including ovals, emerald cuts, and cushions;
Large crystals of peridot have cut gems more than 50 carats in size~27.jpg

26 March 2019

JULY BIRTHSTONES – RUBY  is the most valuable variety of the corundum mineral species, which also includes sapphire. Rubies can command the highest per-carat price of any colored stone. This makes ruby one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red color.
Mineral: Corundum;
Chemistry: Al2O3;
Color: Red;
Refractive index: 1.762 to 1.770;
Birefringence: 0.008 to 0.010;
Specific gravity: 4.00 (+/- 0.05);
Mohs harness: 9;
COLOR: is the most significant factor affecting a ruby’s value: Fine gems are a pure, vibrant red to slightly purplish red;
CLARITY: If a ruby’s inclusions affect its transparency or brilliance they reduce the gem’s value significantly;
CUT: Rubies are commonly fashioned as mixed cuts, which have brilliant-cut crowns and step-cut pavilions;
CARAT WEIGHT: Fine-quality rubies over one carat are very rare and price goes up significantly as size increases~26.jpg

25 March 2019

JUNE BIRTHSTONES – ALEXANDRITE Green in sunlight. Red in lamplight. Color-changing alexandrite is nature’s magic trick. Often described by gem aficionados as “emerald by day, ruby by night,” alexandrite is the very rare color-change variety of the mineral chrysoberyl. Originally discovered in Russia’s Ural Mountains in the 1830s, it’s now found in Sri Lanka, East Africa, and Brazil, but fine material is exceptionally rare and valuable.
Mineral: Chrysoberyl;
Chemistry: BeAl2O4;
Color: Bluish green in daylight, purplish red in incandescent light;
Refractive index: 1.746 to 1.755;
Birefringence: 0.008 to 0.010;
Specific gravity: 3.73;
Mohs harness: 8.5;
COLOR: Fine alexandrite is green to bluish green in daylight and red to purplish red in incandescent light;
CLARITY: Good quality alexandrite has few inclusions. Rarely, needle-like inclusions create a cat’s-eye;
CUT: Alexandrite is most often available in mixed cuts. Its rarity means it is often cut to save weight;
CARAT WEIGHT: Most cut gems weigh less than one carat. Larger, higher-quality gems rise in price dramatically;
JUNE BIRTHSTONES – MOONSTONE A ghostly sheen moves under the surface of this feldspar, like moonlight glowing in water. Moonstone is a variety of the feldspar-group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence. Adularescence is the light that appears to billow across a gem. Other feldspar minerals can also show adularescence including labradorite and sanidine.
Mineral: Feldspar;
Chemistry: KAlSi3O8;
Color: Colorless to White, Gray, Green, Peach, Brown;
Refractive index: 1.518 to 1.526;
Birefringence: 0.05 to 0.008;
Specific gravity: 2.58;
Mohs harness: 6.0 to 6.5;
COLOR: The finest moonstone is a gem of glassy purity with a mobile, electric blue shimmer;
CLARITY: Characteristic inclusions include tiny tension cracks called centipedes;
CUT: As it displays moonstone’s phenomena to best advantage, cabochon is the common cut;
CARAT WEIGHT: Moonstone comes in a wide range of sizes and carat weights~25.jpg

24 March 2019

MAY BIRTHSTONES – EMERALD is the bluish green to green variety of beryl, a mineral species that includes aquamarine. Gem experts differ on the degree of green that makes one stone an emerald and another stone a less-expensive green beryl. Most gemologists, gemological laboratories, and colored stone dealers call a stone green beryl when its color is “too light” for it to be classified as emerald. Even among that group, however, there’s a difference of opinion about what’s considered “too light.”
Mineral: Beryl;
Chemistry: Be3Al2Si6O183;
Color: Vibrant green;
Refractive index: 1.577 to 1.583;
Birefringence: 0.005 to 0.009;
Specific gravity: 2.72;
Mohs harness: 7.5 to 8;
COLOR: The most desirable emerald colors are bluish green to pure green, with vivid color saturation;
CLARITY: In Emerald expect to see inclusions that dealers like to call an internal “jardin,” or garden;
CUT: Due to the crystal shape emeralds are commonly cut as rectangular step cuts called emerald cuts;
CARAT WEIGHT: Because its density is lower, a one-carat emerald will appear larger in size than a one-carat diamond~24

23 March 2019

APRIL BIRTHSTONES – DIAMOND are among nature’s most precious and beautiful creations.
Mineral: Diamond;
Chemistry: C;
Color: Colorless;

CLARITY: The less color, the higher the grade. Even the slightest hint can make a dramatic difference in value;
CUT: Cut (proportions, symmetry, and polish) is a measure of how a diamond’s facets interact with light;
CARAT WEIGHT: Rarity means larger diamonds of the same quality are worth more per carat~23.jpg

22 March 2019

MARCH BIRTHSTONES – AQUAMARINE  Named after seawater, aquamarine’s fresh watery hue is a cool plunge into a refreshing pool. Aquamarine’s name comes from the Latin for seawater and it was said to calm waves and keep sailors safe at sea. March’s birthstone was also thought to enhance the happiness of marriages. The best gems combine high clarity with limpid transparency and blue to slightly greenish blue hues. Like many beryls, aquamarine forms large crystals suitable for sizable fashioned gems and carvings.
Mineral: beryl;
Chemistry: Be3Al2Si6O18;
Color: greenish blue, light in tone;
Refractive index: 1.577 to 1.583;
Birefringence: 0.005 to 0.009;

CUT: Because aquamarine’s color is light, cutting is important and well-cut gems show brilliance;
CARAT WEIGHT: Aquamarine crystals range from tiny to very large—some even up to 100 lbs~22.jpg

21 March 2019

FEBRUARY BIRTHSTONES – AMETHYST  The essence of the color purple, amethyst is beautiful enough for crown jewels yet affordable enough for class rings. Amethyst was as expensive as ruby and emerald until the 19th Century, when Brazil’s large deposits were discovered. It was believed to prevent intoxication—amethystos means “not drunk” in ancient Greek. Today, as the most valued quartz variety, amethyst is in demand for designer pieces and mass-market jewelry alike, and its purple to pastel hues retain wide consumer appeal.

CARAT WEIGHT: Amethyst is available in all size ranges for setting into a variety of jewelry styles~21.jpg

20 March 2019

JANUARY BIRTHSTONES – GARNET  are a set of closely related minerals forming a group, with gemstones in almost every color. Red garnets have a long history, but modern gem buyers can pick from a rich palette of garnet colors: greens, oranges, pinkish oranges, deeply saturated purplish reds, and even some blues. Red garnet is one of the most common and widespread of gems. But not all garnets are as abundant as the red ones. A green garnet, tsavorite, is rarer and needs rarer rock chemistries and conditions to form.

DIAMOND SHAPE Since all diamond cut styles are very different, unique characteristics determine quality for each shape.
Radiant-Cut Diamond:
Trimmed corners are the signature of this diamond, and they help make the radiant-cut a popular and versatile choice for jewellery. A radiant-cut looks equally beautiful set with either baguette or round side-diamonds. Radiant-cut diamonds can vary in their degree of rectangularity. To find the dimension of radiant you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For a radiant diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10;
Pear-Shaped Diamond:
This brilliant-cut diamond is also called a teardrop for its single point and rounded end. The unique look of the pear shape helps make it a popular choice for a variety of diamond jewellery. If you choose an elongated pear shape, the length of the diamond creates a subtle slimming effect on the fingers. To understand what the pear-shaped diamond will look like when viewing it from above, look for the length-to-width ratio on each diamond’s detail page. For the most traditional pear-shaped diamond, look for a length-to-width ratio between 1.45 and 1.75;
Cushion-Cut Diamond:
This unique shape has been popular for more than a century. Cushion-cut diamonds (also known as “pillow-cut” diamonds) have rounded corners and larger facets to increase their brilliance. These larger facets highlight the diamond’s clarity, so if you choose an SI clarity grade, be sure to review the clarity plot on the diamond certificate. Cushion-cut diamonds are available in shapes ranging from square to rectangular. To find the dimension of cushion diamond you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For a cushion-cut diamond that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.15~16.jpg

15 March 2019

DIAMOND SHAPE Since all diamond cut styles are very different, unique characteristics determine quality for each shape.
Asscher-Cut Diamond:
This beautifully unique shape is nearly identical to the emerald-cut, except that it is square. Also, the Asscher-cut diamond shape has a pavilion that is cut with rectangular facets in the same style as the emerald-cut. If you choose SI-clarity be sure to view the clarity plot on the diamond certificate, because this shape highlights the clarity of the diamond. When choosing a colour grade, consider that while the price of a J-colour non-round diamond is exceptional, colour may be slightly visible in its corners. All Asscher-cut diamonds from Blue Nile will appear square, because each one is guaranteed to have a length-to-width ratio between 1.00 and 1.05;
Marquise-Cut Diamond:
The shape of a marquise diamond can maximise carat weight, giving you a much larger-looking diamond. This brilliant-cut diamond looks beautiful set with round or pear-shaped side stones, and the length of the marquise diamond makes fingers appear long and slender. To find the dimension of marquise you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For the most traditional marquise-cut diamonds, look for length-to-width ratios between 1.75 and 2.25;
Oval-Cut Diamond:
An oval diamond has beautiful brilliance that’s similar to a round diamond. Oval diamonds are also very popular as their length can accentuate long, slender fingers. To find the dimension of oval you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the oval diamond’s outline, or what it will look like when viewed from the top. For the most traditional oval-cut diamonds, look for length-to-width ratios between 1.33 and 1.66~15.jpg

14 March 2019

DIAMOND SHAPE Since all diamond cut styles are very different, unique characteristics determine quality for each shape.
Round-Cut Diamond:
The round brilliant cut diamond is by far the most popular and most researched diamond shape available today. For almost 100 years, diamond cutters have been using advanced theories of light behaviour and precise mathematical calculations to optimise the fire and brilliance in a round diamond. In addition to being the most popular and researched shape, round-cut diamonds will typically give you more flexibility in terms of balancing cut, colour, and clarity grades while still getting the fire and brilliance you want. To maximise the brilliance of a traditional round diamond, select one in the two highest cut grades, ideal or very good, and choose ideal, excellent, or very good polish and symmetry grades. For a round diamond with superior sparkle, consider an Astor by Blue Nile™;
Princess-Cut Diamond:
This is our most popular non-round diamond. Its beautiful brilliance and unique cut makes the princess-cut diamond a favourite for engagement rings. The princess has pointed corners and is traditionally square in shape. When choosing a colour grade, consider that while the price of a J-colour non-round diamond is exceptional, colour may be slightly visible in its corners. Also, princess-cut diamonds can vary greatly in how square or rectangular they are. To find the dimension of princess you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. This will determine what the diamond will look like when viewing it from above. Here are length-to-width ratios for princess-cut diamond shapes that are pleasing to the eye. For a princess diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10. For a princess diamond with superior sparkle, consider an Astor by Blue Nile™diamond;
Emerald-Cut Diamond:
What makes the emerald diamond shape different is its pavilion, which is cut with rectangular facets to create a unique optical appearance. Due to its larger, open table, this shape highlights the clarity of a diamond. If you choose an emerald-cut diamond with a lower clarity grade, such as SI, be sure to review the clarity plot on the diamond certificate. Also, emerald-cut diamonds can vary greatly in how rectangular they are. If you’d prefer an emerald cut with a squared outline, look for an Asscher-cut diamond. To find the shape of emerald diamond you want, look for the length-to-width ratio in our interactive diamond search and on each diamond’s detail page. The length-to-width ratio will determine the diamond’s outline, or what it will look like when viewed from the top. For the classic emerald-cut shape, look for a length-to-width ratio between 1.30 and 1.40~14.jpg

DIAMOND CARAT is often misunderstood and refers to a diamond’s weight, not necessarily its size. When comparing diamond carat sizes, take a diamond’s cut into consideration as well: a high-carat diamond with a poor cut grade may look smaller, often cut deeper, than a diamond with smaller carat weight and a better cut;
A Diamond’s Top Diameter:
It is important to measure, in millimeters, the distance across the top (diameter) of the diamond as this is how it is viewed when set into a ring;
A Diamond’s Cut Grade:
A diamond’s cut grade should also be considered. When a diamond is well cut (grades Very Good or higher), the light reflected out of the top making it appear larger;
How do these two Carat Weight factors help when purchasing a diamond:
The diamond’s diameter and cut grade reveal that smaller carat weight diamonds will appear larger with higher cut grades (Very Good and Ideal). On the flip side, a larger carat weight diamond could appear smaller with lower cut grades (Good, Fair and Poor)~13.jpg

DIAMOND CLARITY is the assessment of small imperfections on the surface and internally. The surface flaws are called blemishes, and internal defects are known as inclusions. These tiny, natural blemishes and inclusions are microscopic and do not affect a diamond’s beauty in any way. Diamonds with the least and smallest inclusions receive the highest clarity grades. Clarity is one of the 4Cs of diamond grading and quality. Diamond clarity is the least important factor when choosing to buy a diamond because most diamonds have blemishes and small inclusions that are microscopic, unable to be seen with an untrained or unaided eye.
Flawless (FL) Diamonds:
Inclusions and blemishes aren’t visible on flawless diamonds, even under 10x magnification. Less than 1% of all diamonds are FL clarity. A flawless diamond is incredibly rare because it’s nearly impossible to find a diamond 100% free of inclusions. Six percent of customers buy FL diamonds;
Internally Flawless (IF) Diamonds:
Inclusions aren’t visible in internally flawless diamonds under 10x magnification. Some small surface blemishes may be visible on IF diamonds. Six percent of customers buy IF diamonds;
VVS1, VVS2 Very Very Slightly Included (VVS) Diamonds:
VVS diamonds have miniscule inclusions that are difficult even for trained eyes to see under 10x magnification. VVS2 clarity diamonds have slightly more inclusions than the VVS1 grade. A VVS diamond is an excellent quality diamond and clarity grade. Twenty-one percent of customers buy VVS diamonds;
VS1, VS2 Very Slightly Included (VS) Diamonds:
VS diamonds have minor inclusions that cannot be seen without 10x magnification. VS1 is a higher clarity grade than VS2, which may have some visible inclusions. A VS grade diamond is less expensive than a VVS diamond. Forty-three percent of customers buy VS diamonds;
SI2, SI1 Slightly Included (SI) Diamonds:
Inclusions are noticeable at 10x magnification with SI diamonds, the best value diamonds. With SI1 diamonds, inclusions are sometimes visible to the keen eye without magnification.

DIAMOND COLOUR is the second most important characteristic to consider when choosing a diamond. The highest quality diamonds are colourless, while those of lower quality have noticeable colour, which manifests as pale yellow in diamonds.
The Gemmological Institute of America (GIA) grades diamond colour on a scale of D (colourless) to Z (light yellow or brown). D-Z diamonds are also known as white diamonds, even though most diamonds, including H colour diamonds and G colour diamonds, have varying amounts of colour;
D Colour Diamonds (Absolutely Colourless):
D colour diamond is the highest grade and is extremely rare—the highest colour grade that money can buy. Eight percent of customers choose a D colour diamond;
E Colour Diamond (Colourless):
Like D colour diamonds, E colour diamonds are quite rare and have minute traces of colour largely unnoticeable to an untrained eye. It takes an expert gemmologist to detect the minute traces of colour in this grade. Sixteen percent of customers choose an E colour grade diamond;
F Colour Diamond (Colourless):
Only a gemmologist can detect the minute colour differences between E, F, and D colour diamonds. F colour diamonds are comparable to D or E colour diamonds. The whitest of white diamonds, D-F colour diamonds, pair well with white gold or platinum settings. Twenty percent of customers choose an F colour diamond;
G Colour Diamond (Colourless):
In G colour diamonds, the very slight warm and light yellow tone is difficult to detect unless compared side-by-side with diamonds of better grades. An excellent value, this colour grade pairs well with yellow gold. Eighteen percent of customers choose a G colour diamond;
H Colour Diamond (Colourless):
The faint yellow hue is also difficult to detect in H colour diamonds, which are an excellent value and pair well with yellow gold settings. The colour difference between H colour diamonds and G colour diamonds is very difficult to detect unless compared side-by-side against diamonds of higher colour grades. Fifteen percent of customers choose an H colour diamond;
I Colour Diamond (Colourless):
Still a great value, the slight yellow tint of I colour diamonds are only detected when compared side-by-side with diamonds of H grades or higher. This colour grade also pairs well with yellow gold. Fifteen percent of customers choose an I colour diamond;
J Colour Diamond (Colourless):
A good value, the naked eye can’t easily detect the light yellow tone unless compared side-by-side with diamonds of I grades or higher. J colour grade diamonds pair well with yellow gold ring settings. Eight percent of customers choose a J colour diamond;
K-Z Colour Diamonds (Faint to Light Colour):
From K colour diamonds on, colour is visible to the naked eye. Most feel these diamonds have too much of a warm colour. K colour diamonds are usually half the price of G colour diamonds. Blue Nile does not carry K-Z colour diamonds;
Yellow colour Diamonds:
comes from the presence of nitrogen in their composition. The nitrogen molecules absorb blue light, making the stone a yellow shade. Depending on the amount of nitrogen, a yellow diamond could range from light to dark~11.jpg

DIAMOND CUT is the most important element to consider when buying a diamond. The cut is the biggest factor in creating sparkle and fire, and without a high cut grade even a diamond of high quality can appear dull and lifeless. A diamond cut poorly and too deep can face-up smaller than it actually is;
LESS THAN 1% – Astor by Blue Nile:
Every Astor by Blue Nile Diamond is cut to gather and reflect the most light possible. Light performance is measured by three factors: brilliance, fire and sparkle. Fewer than 15 out of every 10,000 diamonds qualify as an Astor by Blue Nile diamond;
TOP 3% – Ideal Cut:
This rare cut represents roughly the top 3% of diamond cut quality. It reflects most light that enters the diamond;
TOP 15% – Very Good Cut:
This cut represents roughly the top 15% of diamond cut quality. It reflects nearly as much light as the ideal cut, but for a lower price;
TOP 25% – Good Cut:
This cut represents roughly the top 25% of diamond cut quality. It reflects most light that enters, but not as much as a Very Good cut grade;
TOP 35% – Poor/Fair Cut:
Represents roughly the top 35% of diamond cut quality. These diamonds tend to appear dull or glassy. Low grade not offered by Blue Nile~10.jpg

The main highlight of the Galaxy Fold is that it has two displays — one on the outside and another that’s revealed when you open the phone up.
The outer display is a 4.6-inch HD+ Super AMOLED panel with a 21:9 aspect ratio. The inner/main display of the Galaxy Fold is a large 7.3-inch QXGA+ Dyanic AMOLED canvas with a form factor of 4.2:3.
You can use the outer display for anything you’d regularly use your phone for, including texting, making calls, spending endless hours on Twitter, you name it. However, the big draw to the Galaxy Fold is that you can open it up and get a tablet-like experience in a device you can easily fit in your pocket~8.jpg

HUAWEI MATE X even managed to turn some sceptics into bendy phone believers. Foldable screens aren’t like notches. They’re not just some incremental stepping stone on the way to achieving a bigger goal like an all-screen phone. Flexible displays have the power to transform the way people create and design entire categories of gadgets, most notably wearables and phones~6.jpg
