Sans Pareil Boleite Colorful Gemstones




Boleite was very first discovered in Boleo, Mexico in 1891, in a location on the Baja peninsula that is becoming recognized for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.

The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.

Boleite's refractive index is also quite high at 2.03-two.05; greater than sapphire, sphene and demantoid garnet.

Besides cumengite, there are a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
