Amethyst is the most widely used quartz crystal and has a distinct characteristic purple colour.
These are beautiful natural stones that have not been tumbled or polished.
Amethyst is a purple coloured quartz crystal which obtains it colour from irradiation, impurities of iron or in some cases other transition metals and the presence of other trace elements. Quartz is a silica mineral with chemical formula SiO2.
These stones are crystals (or a number of fused crystals) but do not have the characteristic 6-sided quartz structure with pyramid terminations. They are randomly shaped and hence we class them as stones.
We also sell amethyst crystals which do have the characteristic crystal structure. You will find these under Natural Crystals in this website.
Size Descriptions for all Bastion Paint Crystals and Stones

Where items are approximately spherical the size refers to their diameter. Where items are long and thin (such as crystal or blade shapes) or any other shape, then the size refers to their largest dimension.

Our pictures do not showcase the best, they are as realistic as possible and include a R1 coin to demonstrate the actual size.
