The cut grade of any diamond refers to the proportions of the facets to facilitate light reflection.
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 super-ideal diamond reflects more white light back than any other diamond cut we offer.
