Lustre (British English) or luster (American English; see spelling differences) is the way light interacts with the surface of a crystal, rock, or mineral. The word traces its origins back to the Latin lux , meaning "light", and generally implies radiance, gloss, or brilliance.
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
Murdochite is an opaque mineral that exhibits a black color, adamantine luster, black streak, and isotropic optical class. [11] Samples from T. Khuni mine indicate that polished sections of murdochite resemble the color and reflectivity of magnetite but vary because of zoning. [10]
The average cloud weighs over one million pounds. Wearing a necktie could reduce blood flow to your brain by up to 7.5 percent. Animals can also be allergic to humans.
One of three stable transuranic elements predicted by the new science of nucleonics in James P. Hogan's Giants series. Not naturally occurring outside of neutron stars, but trace amounts are created at the detonation of nucleonic weapons. Bureaucratium Scientific in-joke: Similar to Administratium and variation of the joke.
Transparent zircon is a well-known form of semi-precious gemstone, favored for its high specific gravity (between 4.2 and 4.86) and adamantine luster. Because of its high refractive index (1.92) it has sometimes been used as a substitute for diamond, though it does not display quite the same play of color as a diamond.

In textiles, lustre or luster is a physical property that makes them appear bright, glossy, and shiny. The amount of light reflected from the surface of a fiber is referred to as its luster. The level of luster is determined by how light reflects off the surface. For example, round surfaced fiber reflects more light and appears shinier than ...
