Detailed explanation-1: -We use the term adamantine to describe crystals that sparkle or appear brilliant; diamond (C) is perhaps the best-known example.

Detailed explanation-2: -diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications. *Estimate.

Detailed explanation-3: -A brilliant luster such as the sparkling reflection of diamond is known as adamantine. Minerals of adamantine luster have high refractive indices (1.9-2.6) and are highly dispersive and translucent.

Detailed explanation-4: -The luster of a diamond is described as ‘adamantine’, which simply means diamond-like. Reflections on a properly cut diamond’s facets are undistorted, due to their flatness. The refractive index of diamond (as measured via sodium light, 589.3 nm) is 2.417. Because it is cubic in structure, diamond is also isotropic.

Detailed explanation-5: -A mineral has a definite chemical composition. This means that every occurrence of the substance has the same chemical composition and that it is uniform throughout each occurrence. Diamonds are made entirely of carbon so they easily fall into this category. A mineral has an ordered internal structure.
