corundum, anorthite and biotite. A crystallo-chemical enigma, it is one of the few rock-forming minerals with unknown crystal structure.

While Hiddenite is usually one of the lower-priced minerals, this crystal from Afghanistan was ... It’s made as a branching plant-like structure by marine creatures that live in colonies.

In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ...

Using corundum as the reference material also facilitates analysis ... of choice for analyzing systems containing extremely disordered phases for which no crystal structure is available. Similarly, ...
