Introducing Astor by Blue Nile™

We’ve got something exciting to share: Astor by Blue Nile™ diamonds, a brand-new level of brilliance.

Our diamond team is always on the lookout for diamonds that blow us away with their quality and characteristics. And while all of our diamonds are beautiful, the ones in our newest collection, Astor by Blue Nile™, are cut specifically for brilliance.

Every Astor by Blue Nile™ diamond is graded by GIA and certified by GemEx to unlock an unmatched brilliance. We asked for diamonds that catch the eye from across the room, and our diamond team did not disappoint.

Cut is Critical

Cutting a diamond from its rough form is the most crucial step in creating a diamond with extraordinary brilliance. It begins with premium quality rough stone with as few impurities or inclusions as possible. The rough is then precisely cut for ideal proportions and symmetry. If a diamond is cut even slightly out of proportion, whether too shallow, wide, deep, or narrow, it will restrict the amount of light that can be returned to the eye. In addition, precise symmetry ensures that each mirror-like facet is evenly aligned to reflect the maximum amount of light. Astor by Blue Nile™ diamonds are cut specifically to maximize light performance.

What is Sparkle?

A diamond is comprised of facets, or tiny mirrors, that reflect light. As a diamond rocks back and forth, each individual facet comes alive with flashes of brilliance (white light) and fire (colored light). This display is known and measured as sparkle. Every Astor by Blue Nile™ diamond is specifically cut to achieve a noticeable sparkle.

Exceptionally rare, only 1 in 1,000 diamonds qualify as an Astor by Blue Nile™ diamond.

While we have absolute confidence in the striking brilliance of an Astor by Blue Nile™ diamond, it’s best to let them speak for themselves:
