Gem Minerals
Borosilicate
What it is
Minerals containing both boron and silicon in their structure. Danburite is a clear, brilliant borosilicate often mistaken for diamond. Jeremejevite is one of the rarest gem minerals on Earth.
How it forms
Forms in boron-rich pegmatites and metamorphic environments. Danburite commonly occurs in evaporite deposits, while jeremejevite forms in aluminum-rich pegmatites.
Boron + silicon oxide frameworks
