Amethyst from Minas Gerais, Brazil
Amethyst is pretty much the most well known mineral and gemstone in the world. It is the purple variety of the mineral Quartz. Amethyst comes in a variety of different shades of purple depending on the locality, usually caused by impurities of iron or manganese compounds.
I have several specimens of amethyst from around the world including Australia, Brazil and Nigeria. This piece is particularly special due to its formation known as elestial amethyst. Elestial crystals are multi-layered or etched quartz crystals with lots of small terminated crystal formations all over it. Two common formations are a step and repeat pattern or the look of lots of small crystals all stuck together on the outer surface of the crystal. This specimen shows traces of deep purple at the tips and has smoky zones throughout.
The location of this elestial specimen is unknown, however talks with Tony from Mineral Store Australia suggest it may be Brazilian. Typical location for Brazilian amethyst is Minas Gerais.
Although amethyst is very common and found in many location, is it quite rare to find elestials of this quality.
Anyone who may be able to add some info to this specimen, please get in touch with me.
