THE AMETHYST : A ROYAL VIOLET...
In ancient times, amethyst was already being engraved and cut into sculptured forms, witness the bust of Trajan which Napoleon captured in Berlin. Amethyst quartz, banded with whitish layers, is particularly good to work with, though it is only ever either translucent or opaque or somewhere in between. In earlier times, people liked to drink wine from amethyst cups, which brings us back to the stone's protective function against alcoholism. According to the ancient Greek saga, Diana turned a nymph whom Bacchus loved into an amethyst; hence the term Bacchus stone. Anyone wishing to protect a drunkard from delirium mixed some pulverised amethyst into the person's drink.

ORIGINES... The deposits with the greatest economic significance are in various states in southern Brazil and in neighbouring Uruguay. The third major export country is Madagascar. However, this gemstone is spread all over the world. Good specimens were found in Aztec graves, though the deposits from which they were extracted are no longer known today. On the Canadian side of Lake Superior in North America, there is a place named Amethyst Harbor. The violet quartz is found there in ample quantities, though rarely in gemstone quality. The fame of Idar-Oberstein, the German gemstone centre, is based on domestic amethyst finds. In earlier times, raw material was delivered there from the Zillertal Alps. When these nearby deposits ceased to yield, the old cutters' tradition was able to be preserved thanks to supplies organised by German emigrés in South America. Russian amethysts, which were mainly mined in winter in the Urals, were once famous for their particularly beautiful colour, which shone magnificently even in artificial light. In Tibet there were amethyst rosaries, for there the gemstone was dedicated to Buddha and was said to promote clarity of mind. In Sri Lanka, stones which have rolled down on their own are found in debris.However, the amethyst is more likely to turn up in spaces lining agate almonds and druses in igneous rocks. What was presumed to be the largest-ever cavity was discovered in 1900 in Rio Grande do Sul. The almond measured ten by five by three metres (33 by 16 by 10 ft.) and weighed an estimated eight tonnes. The dark violet amethysts, some as large as a man's fist, may have weighed some 700 cwt. altogether. There is a piece weighing 200 kilogrammes, taken from this Brazilian treasure, in the Washington Museum. In recent times, a find in the USA has been making headlines. In July 1993, a three-metre druse was found in Maine, which contained well over 1000 kilogrammes of cuttable amethyst, some of it in crystals 19 cm in length.The South American deposits in particular, which were not discovered until the nineteenth century, brought down the price of the violet gemstone. The amethyst bracelet of Queen Charlotte of England, which was so famous at the beginning of the 18th century, its value being estimated at 2000 pounds sterling at that time, was apparently worth only 100 pounds 200 years later. However, the price has a close relationship with the quality, and the quality varies immensely. Most of the material from Brazil is light-coloured, a tender purple. In Madagascar, it is generally red or violet hues which are found. Uruguay supplies the most beautiful and the deepest colour, but it is mostly blemished. Thus immaculate stones of the finest violet still fetch carat prices of well over a hundred euros. Mounted with diamond braid trimming, as has been the custom for some 100 years, enchanting pieces of jewellery are thus created. No wonder that people find it worth going to the trouble of producing imitations and synthetics.
