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;
