Amethyst

Chemical Formula SiO2

Amethyst comes from the Quartz family. It gets its violet because of the presense of the trace element iron and aluminium. Amethysts naturally occur in nature and are not treated. Major sources of Amethyst are USA, Brazil, South Korea, Russia and Austria.

We carry Amethysts in calibrated sizes in several shapes such as rounds, ovals, marquise, cushions, etc in various sizes. For more information on the sizes we usually keep in calibrated sizes, please click here.

We can also cut precision cut Amethyst, this is finely cut and crafted to bring the maximum brilliancy into it. This is done with the help of automated machines and skilled labour. For your demands in precision cut, please contact us for more information.

We can accomodate pairs, layouts and single unique Amethyst. Also perfected is the art of special cuts or custom cuts. This is suited to fit your specifications and can be any shape and/or cut of your choice. For your requirements, please contact us.
