Imagine blue cheese set in stone, and you are picturing the visual appearance of this gem. It has an almost plant-style appearance to it, detailed with colourful speckles due to the presence of chrome or iron.
This opaque gemstone is normally tumbled or cabochon cut and as it will normally have a large carat weight, it is ideal for setting in big-look necklaces and bracelets.
Moss Agate is a member of the Chalcedony group of gems, who in turn belong to the Cryptocrystalline family of Quartz. It is rarely set in jewellery and is popular with both mineral and gem collectors alike.
