Adamantine to waxy luster are the words used to describe the luster of diamonds.

According to Wikipedia:

"Adamantine minerals possess a superlative lustre, which is most notably seen in diamond. Such minerals are transparent or translucent, and have a high refractive index (of 1.9 or more)."

Luster is the clarity and refractivity of an individual stone. Not all diamonds are created equal. Flawless diamonds are extremely rare and can be prohibitively expensive for most of us. In jewelry, generally diamonds evaluated as those containing VVSI (very very slightly included) to SI2 (two slight inclusions), are more affordable. SI2 is generally the lowest grade for good gems. Inclusions can be any imperfection.

The luster is its refractiveness. Its ability to bounce back available light from inside the stone. This can be affected by the color, cut or clarity. Only 20% of all diamonds mined are gem-stone quality.
