Beautiful amethyst double terminator

A hand-cut double-terminated amethyst from Brazil with points at both ends. The crystal combines the violet amethyst color with enclosed white quartz zones and displays beautiful natural inclusions.

Amethyst (SiO₂) is a quartz variety of the trigonal crystal class. In double terminators, crystal points grow from both poles, which is rarer in nature than single termination. Brazilian double terminators are classic collector's items.

The combination of amethyst and milky quartz within the same crystal documents changing growth conditions during formation. A handy, compact piece with clear mineralogical significance.
