Adamantine luster is a term used to describe a shiny, brilliant, and reflective luster on minerals or gemstones. It is often associated with diamond-like or metallic sheen, indicating a high level of light reflection and clarity in the material.
Diamond is a familiar mineral that exhibits adamantine luster. Its exceptional hardness and perfect cleavage contribute to this distinctive luster, giving it a brilliant shine and sparkle.

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.
Luster on a diamond appears as a bright, reflective quality that gives the diamond a shiny and sparkling appearance. It is a result of the diamond's ability to reflect light due to its superior optical properties, such as high refractive index and dispersion.
Adamantine is a mineral, often referred to as adamantine spar. It is a silky brown form of corundum. It has a Mohs rating of 9. Adamantine is also used as an adjective to refer to non-metallic, brilliant light reflecting and transmitting properties, known as adamantine luster. Diamond is the best known material to be described as having adamantine luster, although anglesite, cerussite and corundum in some of its forms are also described in this way.Adamantine can also refer to any fictitious or mythological material that is extremely hard (often at least as hard as diamond) or has some other special properties.
