From the Minerals site, below: "The luster of Diamond is excellent. Diamond exhibits great fire and brilliance, which gives it a shiny, freshly polished look. Rough Diamonds exhibit a greasy luster, but proper cutting give them a powerful adamantine luster. "Only synthetic substances and a few minor gemstones can reach or excel the refractive index of Diamonds."
Diamond luster is described as adamantine to waxy. Adamantine luster is described as "...non-metallic, brilliant-light-reflecting and transmitting properties of minerals..." and is not limited to diamonds.
Diamonds are adamantine to waxy in luster. Diamonds come in all colours, and varying shades of colours, including yellows, browns, grays, and also white, blue, black, reddish, greenish and colorless.
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.
Fake diamonds such as rhinestones, zircon, and cubic zirconia don't lose luster over time, but the problem is that they don't have near the luster of the real thing in the first place. So in one way, you could say they never had an attractive appearance to lose.

No. Waxy is similar to the sheen on an unburnt candle's surface (hence, waxy). A cut diamond's luster is considered to be adamantine.Another AnswerDiamond's luster is considered to be adamantine to waxy, depending on the state of the stone. A raw stone or one better used in industrial applications could tend to be more waxy; a gem-quality, cut and polished stone to be adamantine.
It is the hardness factor which makes difference in stones to gemstones it is the hardest natural stone , and so does not gets scratches so remains brilliant, and luster.
The tests you can do is the streak test, the luster test,the finger nail test(which is scratching it ti see if its hard or not).
