1" Amethyst Cacoxenite Oval Cabochon

This is a beautiful, 1" tall "amethyst cacoxenite" cabochon. This material was collected from Brazil and is truly gorgeous, especially when viewing under magnification. There is debate as to whether the inclusions within the amethyst are cacoxenite or goethite since the likelihood of a phosphate mineral (cacoxenite) forming within amethyst is very slim. Either way, this specimen is truly eye catching.

Amethyst is a purple variety of quartz (SiO2) and owes its violet color to natural irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It’s considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires and rubies. The largest and best known amethyst deposits occur in southern Brazil and Uruguay but many localities around the world produce an amazing variety of amethyst crystals and formations.
