Amethyst 4.20ct

Amethyst is a violet variety of quartz. It occurs in the full range of violets. From almost colorless to dark violet. In the best specimens it has flashes of red and blue. When an amethyst presents a dark violet with sparkles, it is commercially called 'Siberian color' since specimens of great beauty came out of Siberia.

It has Mohs hardness 7 and can be safely used for durability.

It has been sintered successfully with great success and it is very difficult to distinguish the synthetic from the natural one.

A very high percentage of those for sale in the market are synthetic, which is why it is a gem that must be purchased from a very reliable supplier.

The main deposits are in: Uruguay, Brazil, Bolivia, East Africa, Russia.

In Catalonia, the amethysts of Montseny (Barcelona) were very important.
