Geology / History

Named for Danbury, Connecticut, U.S, where it was first discovered by Charles Upham Shephard in 1839. Danburite typically occurs as a Calcium Boron silicate mineral, in granite & metamorphosed carbonate rocks associated with hydrothermal activity & in evaporates.

The Dana classification system categorises Danburite as a Sorosilicate & the Strunz classification system lists it as a tectosilicate, its structure can be interpreted as either.

Because of its high refractive index, well cut Danburites are remarkably bright & look something like diamonds. Today most of the colourless Danburite comes from Mexico.
