We stock Amethyst Crystals from our mines here in Australia, and from many other countries.
A member of the Quartz family of crystals, amethyst is popular with Lapidarists, Crystal healers, and even interior designers!
Amethyst is one of the most popular gems, and has been for thousands of years.
Amethyst is one of the rarer forms of Quartz, but is not especially uncommon, with a nearly global distribution.
Like all gems, the fine quality material is hard to find.
The best quality is generally found in Russia and Uruguay, fine gems sometimes exhibit a red secondary flas- with this type of material being called Siberian in the gem trade.
Siberian quality can command more than $100 per carat at retail for cut stones.
Synthetic Quartz is widely available and very difficult to identify except in a well equipped gemological laboratory.
For this reason, many collectors prefer to buy rough material and have it cut in order to have an assured provenance.
Amethyst is a violet variety of quartz often used in jewelry. The name comes from theAncient Greek ἀ a- (“not”) and μέθυστος méthystos (“intoxicated”), a reference to the belief that the stone protected its owner from drunkenness. The ancient Greeks wore amethyst and made drinking vessels decorated with it in the belief that it would prevent intoxication. It is one of several forms of quartz. Amethyst is a semiprecious stone and is the traditional birthstone for February.
Amethyst is a purple variety of quartz (SiO2) and owes its violet color to iron impurities (in some cases in conjunction with transition element impurities), and the presence of trace elements, which result in complex crystal lattice substitutions. The hardness of the mineral is the same as quartz, thus it is suitable for use in jewelry.
Amethyst occurs in primary hues from a light pinkish violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and blue. The best varieties of amethyst can be found in Siberia, Sri Lanka, Brazil and the far East. The ideal grade is called “Deep Siberian” and has a primary purple hue of around 75–80%, with 15–20% blue and (depending on the light source) red secondary hues. Green quartz is sometimes incorrectly called green amethyst, which is a misnomer and not an appropriate name for the material, the proper terminology being prasiolite. Other names for green quartz are vermarine or lime citrine.
Of very variable intensity, the color of amethyst is often laid out in stripes parallel to the final faces of the crystal. One aspect in the art of lapidary involves correctly cutting the stone to place the color in a way that makes the tone of the finished gem homogeneous. Often, the fact that sometimes only a thin surface layer of violet color is present in the stone or that the color is not homogeneous makes for a difficult cutting.
