As February's birthstone, it is traditionally gifted to mark birthdays, anniversaries, and other significant milestones. The sources provided illustrate the gemstone's integration into modern jewelry, with a wide array of pieces available, from simple solitaire rings to elaborate statement necklaces. The pricing, as indicated, varies significantly, reflecting differences in quality, size, and craftsmanship. While the sources do not delve into the gemological specifics, the amethyst's properties are well-documented in gemological literature. It is a variety of crystalline quartz, with a hardness of 7 on the Mohs scale, making it durable enough for everyday wear. Its chemical composition is silicon dioxide (SiO₂), and its characteristic purple color is attributed to iron impurities and natural irradiation.
The historical lore surrounding amethyst is particularly rich. Ancient civilizations, including the Egyptians and Greeks, believed the stone could prevent intoxication and clear the mind, leading to its association with sobriety and clarity. The name "amethyst" itself is derived from the Greek word "amethystos," meaning "not intoxicated." This belief persisted for centuries, with amethyst often being used in drinking vessels and amulets. Beyond its connection to sobriety, amethyst was also considered a stone of spirituality and calm, used by clergy and royalty to signify piety and power. Its purple color, once as rare and precious as emerald and ruby, was reserved for the upper echelons of society, further cementing its status as a gemstone of nobility and luxury.
Geologically, amethyst forms in geodes and cavities within volcanic rocks. Major sources have historically included Brazil, Uruguay, and Zambia. Brazilian amethyst, particularly from the state of Rio Grande do Sul, is known for its large, deep-colored crystals. Zambian amethyst often exhibits a reddish secondary hue, while Uruguayan amethyst is famous for its deep, saturated color and is sometimes found in the form of "amethyst cathedrals"—massive, hollow geodes lined with crystals. The formation process involves silica-rich fluids depositing layers of quartz in cavities over millennia, with the purple hue developing due to the presence of iron and natural irradiation. The most prized amethyst exhibits a deep, uniform purple color with minimal zoning, though lighter and darker variations are common and also valued in different markets.
In terms of gemological properties, amethyst is a member of the quartz family, with a Mohs hardness of 7, a trigonal crystal system, and a vitreous luster.

History and Lore
The historical significance of amethyst is deeply rooted in ancient cultures. The Greeks believed that amethyst could ward off the effects of alcohol, and they often carved drinking vessels from the stone. The Roman philosopher Pliny the Elder, in his Natural History, noted that amethyst was used to prevent intoxication and to soothe the mind. This association with sobriety gave rise to the gem's name, derived from the Greek amethystos, meaning "not drunk." Beyond its practical uses, amethyst was also revered for its spiritual properties. It was considered a stone of piety and humility, often worn by religious figures and royalty to signify their connection to the divine and their elevated status.
During the Middle Ages, amethyst was a symbol of royalty and was frequently used in the crowns, scepters, and jewelry of European monarchs. Its purple hue, which was once as costly as ruby and emerald, made it a natural choice for those in power. The stone's color was associated with the "divine right" of kings and the nobility of spirit. In the Christian church, amethyst was used in bishop's rings and as a symbol of Christ's suffering, further cementing its spiritual significance. This historical reverence for amethyst has carried into the modern era, where it remains a symbol of luxury, peace, and tranquility.
The transition of amethyst from a rare, exclusive gemstone to a more accessible one occurred in the 19th century with the discovery of vast deposits in Brazil. These new sources flooded the market, making amethyst more affordable and allowing it to become a mainstream gemstone. Despite this, its historical allure and symbolic meanings have remained intact, and it continues to be one of the most beloved gemstones for both personal wear and gifting.
Geological Formation and Sources
Amethyst is a variety of quartz, which is one of the most abundant minerals on Earth. It forms in geodes and cavities within volcanic rocks, where silica-rich fluids slowly deposit layers of quartz over millions of years. The distinctive purple color is caused by the presence of iron impurities within the crystal lattice, combined with natural irradiation. The degree of color saturation depends on the concentration of iron and the intensity of the irradiation.
Historically, the finest amethyst came from Siberia, but these deposits are now largely depleted. Today, the primary sources of amethyst are Brazil, Uruguay, and Zambia. Brazilian amethyst, particularly from the state of Rio Grande do Sul, is known for its large, deep-colored crystals and is the most common source in the market. Uruguayan amethyst is famous for its deep, saturated purple color and is often found in the form of "amethyst cathedrals"—massive, hollow geodes lined with crystals that can weigh several tons. Zambian amethyst, which is mined in the Copperbelt region, often exhibits a reddish secondary hue and is prized for its rich color.
Other sources include Namibia, Mexico, and the United States (specifically Arizona and North Carolina). However, the bulk of the world's amethyst supply comes from South America. The mining process often involves extracting geodes from volcanic rock, which are then cracked open to reveal the crystal formations inside. The crystals are then cut, polished, and shaped for use in jewelry.
Gemological Properties
Amethyst is a member of the quartz family, with the chemical formula SiO₂ (silicon dioxide).
