The mining for these stones involves going deep underground into that potential quartz crystal sources. ![]() Amethysts are known to undergo a process of growth: where the specific mineral expands, accretions give volume to the mineral stone, becoming larger. ![]() Amethyst crystals are found in geological formations known as geodes: These geodes are found in various parts of the rock formation and tend to be covered in various mineral forms. The hardening and cooling of magma deep within the Earth’s surface that becomes basalt are where quartz crystal formations tend to concentrate. Amethysts crystals are found in hardened magma that resulted from volcanic activity that took place millions of years. To understand the nature of amethyst mining one must look at the stone’s origins. (Pics of Amethyst mining) Amethyst MiningĪmethysts are mined in a number of countries, however the most notable is Brazil, where the mining of this stone has been well documented. Today amethysts hold their own as top precious stones, that follow the lead of the top four, notably purple sapphires as the more affordable purple gemstone option. However, despite the rise in new competition from other parts of the world, Brazilian amethysts continue to hold the lead. The real challenge however came from Africa, with South Africa leading the way, with the quartz variety of these gemstones being notable for their vividity, and tone. In time new amethyst deposits were discovered in other parts of the world, with countries like Russia and even India entering the mix. Further, in the world of precious stones, the demand for amethysts was not as significant as diamonds and to a lesser extent sapphires held the lead. Following the discovery of these deposits in the early part of the 19 th century the supply of the famous purple gemstone began to increase, considerably to a point where the supply grew to an extent that began to impact the prices of the stone. The state of Rio Grande do Sul in the south of Brazil is the most notable centre for this stone type, with the region in north Ametista, do Sul (a place which literally has the word amethyst in it). The most notable country in the amethyst equation is Brazil, with the discoveries of deposits of quartz deposits, the family of which amethysts are a part. Which led to the growing influx of the supply of the stone into the market. Things started to change with the discovery of major quartz deposits of the gemstone variety in South America. A position that has been built on the historical rarity of natural purple gemstones, including the rarity of the purple version of the quartz crystal. With the characteristic colour of purple, amethysts today are the choice purple gemstones in the market. Amethysts have been recognised for their beauty and then a rarity in many parts of the world, and have continued to hold their position as one of the top gemstones in the world. Most notable here is the reference to amethyst stones in Scripture, where amethyst was among the twelve stones that represented each of the twelve tribes of Israel. The trademark purple gemstone found its home in the classical period of ancient Greece and Rome and later was recognised in the Christian traditions of old. History of Amethyst UseĪmethyst gemstones have a long history of use that goes back thousands of years. Here we will outline the main features of the amethyst stone: a short history of the stone, the mining of amethyst, amethyst meaning, the key characteristics and properties of amethysts and a general guide on buying amethyst jewellery. The February birthstone amethysts are recognised by their rich purple colour. Amethyst’s are members of the quartz family of gemstones a silicon dioxide SiO 2: which is one of the more abundant minerals on Earth, unlike conundrums, amethysts are known for their versatility and is employed in many spheres most notably in the fine jewellery industry. ![]()
