FAQs about Astor Cut Diamonds

The cut grade of any diamond refers to the proportions of the facets to facilitate light reflection.

Blue Nile offers four cut grades: Good, Very Good, Ideal, and Astor by Blue Nile™. There is also a Poor/Fair grade, but you'll never find it at Blue Nile.

There are three terms you'll hear in reference to a diamond's cut, including brilliance, fire, and scintillation. Brilliance refers to light reflection, fire is the dispersion of light into the colours of the rainbow, and scintillation is the contrast between the light and dark areas.

Our rarest and most expensive cut is the Astor by Blue Nile™. This diamond reflects more white light back than any other diamond cut we offer.

Astor Ideal Cut Round Diamond Review

Scintillating, absolutely stunning!

I went for the Astor Ideal cut and they are just spectacular. The glow with inner fire. They sparkle and shine even in dim light! Purchased for myself--not an engagement ring but the style which is nicely low profile would be suitable for any situation.

Top-notch customer service and on top of everything was the diamond ring. It was so eye-catching, and I have got so many compliments about it, so far. Thank you Blue Nile, again, your product's quality and your customer services did help me a lot in choosing the best style and the quality of the diamond for myself.
