Three beautiful pieces of the mineral amethyst from South Africa. Each stone boasts rich purple colour but some colour zoning can also be seen. Colour zoning which is quite common in amethyst means there's a variation in colour within the crystal. The difference in colour can be so subtle it's hardly noticeable or in the most extreme examples the quartz can be colourless or white. The milky white colouration in chevron amethyst is the result of colour zoning.
The rich purple colour of amethyst has long been associated with royalty and this tantalising mineral has been in great demand throughout history. Some of world's finest amethyst crystals have been set into royal jewellery collections from Ancient Egypt to the British Crown Jewels.
The Ancient Greek philosopher Theophrastus wrote in detail about the mineral amethyst and noted it changed colour when exposed to fire. Heating a mineral can change its chemical composition which can bring about a subtle or distinctive change in colour. A significant amount of commercial grade citrine is in fact heated amethyst. Most of the world's finest rubies and sapphires are also heated to enhance or change their colour.
The name amethyst is believed to have come from the Ancient Greek words for 'not' and 'to intoxicate' because the stone was believed to protect against intoxication. For this reason drinking cups were often carved from amethyst. In the early Christian church it was treated as a symbol that represented the sobering state that all bishops must adhere to. An amethyst stone then started being worn as part of the bishop's regalia. This tradition has continued until today and the ecclesiastical ring worn by many bishops usually features an amethyst.
