Danburite was discovered by Charles Upham Shephard (1804-1866), an eminent American mineralogist who was, for many years, a professor of natural history at Amherst College. Discovered in Danbury, Connecticut, danburite is still mined there today.

Danburite usually ranges from colorless to very light pink, but some deposits may produce specimens in shades of light yellow or brown. Danburite is known for its excellent transparency and clarity.

By chemical composition, danburite is a calcium aluminum borate silicate. It is quite hard, with a rating of 7 to 7.5 on the Mohs scale.

Since it has a reasonably high refractive index (6.30 to 6.36), in the same range as tourmaline, the faceted material looks very good. Danburite has very little cleavage, so it is easy for lapidaries to cut. Its density is 2.97 to 3.03, which is about the same as jadeite.

Danburite has very powerful spiritual properties and serves as a protector that brightens up the mind of the owner. Danburite, in a clean gem form, is extremely rare in nature and is no longer mined in appreciable quantities.
