Serendibite is considered to be a very, very rare gemstone. It was discovered in 1902 and is named after the old Arabic name for Sri Lanka: Serendib. Serendibite is a hardness 6-7, may be transparent to translucent, and has a vitreous luster. it may be black, dark blue, grayish-blue, pale yellow, blue-green, blue, or brown. In transmitted light it may appear near colourless to yellow-green or blue. Serendibite has a triclinic crystal structure and may occur as granular anhedral to subhedral crystals in a matrix, or as twinned crystals. On occasion, but rarely, Serendibite may be found as tabular crystals. Serendibite is found in only a couple locations in Burma (Myanmar), Russia, Madagascar, Sri Lanka, Tanzania, and the states of New York and California. Serendibite can be extremely expensive. I have seen some outrageously high per carat values quoted on a couple of sites, I am doubtful on the accuracy of those quotes. However, you should still expect to spend quite a lot of money for good examples as facet quality stones are rare.
