History and Lore
The historical narrative of amethyst is as vibrant as its color. Its name is a direct link to ancient Greek culture, derived from the word amethystos, which translates to "not drunk" or "not intoxicated." This etymology reflects a core belief held by the ancient Greeks: that amethyst could prevent intoxication and promote a clear, sober mind. To harness this perceived power, the Greeks carved drinking vessels from the stone and wore amethyst jewelry during feasts, believing it would ward off overindulgence and maintain mental clarity. This association with Bacchus, the god of wine, further cemented its role in classical mythology.
The admiration for amethyst was not confined to Greece. The ancient Romans also held the gemstone in high esteem, continuing the tradition of using it in drinking vessels and ornamental jewelry. Beyond the Western world, amethyst has a long and storied history in other civilizations. The Egyptians, for instance, utilized the stone, and it was often considered a symbol of wealth and power. Over the centuries, amethyst's status fluctuated. At one point in history, it was a gem reserved for royalty, a privilege that underscored its value and desirability. This regal connection is exemplified by figures such as Catherine the Great of Russia, who was known for her penchant for the stone, adorning herself with amethyst necklaces, earrings, and other ornaments.
The journey of amethyst to its modern status as the official February birthstone is rooted in both tradition and modern gemological classification. Its deep, wine-like color and historical ties to clarity and protection made it a natural fit for the month associated with introspection and renewal. The gem is also traditionally given as a gift for the sixth wedding anniversary, symbolizing the enduring and clear-headed nature of a long-term partnership. Renaissance Europeans even attributed calming properties to the stone, believing it could soothe lovers overrun by passion, adding another layer to its complex symbolic history.
Geological Formation and Sources
Amethyst is a variety of the mineral quartz, which has a chemical composition of silicon dioxide (SiO₂). Its formation is a geological process that typically occurs within geodes—hollow, spherical rock formations—found in cooled lava flows. The distinctive purple color of amethyst is the result of trace amounts of iron and other impurities within the quartz crystal lattice, combined with natural irradiation from the surrounding rock. This irradiation, occurring deep within the Earth's crust, causes the iron atoms to shift their electron states, which in turn produces the characteristic purple hue.
The color distribution in amethyst can be uneven, often showing color zoning or bands. This natural variation is a key identifier and adds to the stone's unique character. The specific shade of purple can range widely, from a pale lilac to a deep, reddish purple. The most prized stones are typically those with a rich, saturated color and minimal color zoning.
While amethyst can be found in various locations around the globe, specific mining locations mentioned in the provided sources are not detailed. However, it is widely known in the gemological community that significant sources include Brazil, Uruguay, Zambia, and South Africa. The stones from different localities can exhibit subtle variations in color and clarity. For example, some Brazilian amethysts are known for their lighter, more pastel hues, while Uruguayan deposits often yield deeper, more intense purple tones. The availability of amethyst is relatively widespread, which contributes to its accessibility for consumers. The stone can be mined from natural deposits or synthesized in laboratories, with both natural and lab-created varieties being used in jewelry. The gem's presence in the collections of royal families throughout Europe and Asia further attests to its long-standing historical and geographical significance.
Gemological Properties
Understanding the physical and optical properties of amethyst is essential for both identification and appreciation. As a member of the quartz family, it shares many characteristics with other varieties, but its color sets it apart.
Chemical Composition and Crystal System: Amethyst is silicon dioxide (SiO₂). It crystallizes in the trigonal crystal system, forming hexagonal prisms terminated by pyramids.
Color and Cause: The defining feature of amethyst is its purple color, which ranges from light lilac to deep violet. The color is caused by the presence of iron impurities and natural irradiation. It is important to note that heating amethyst can alter its color. When heated to certain temperatures, amethyst can turn yellow, green, blue, or red-orange. These heated stones are no longer classified as amethyst but become different colored quartz varieties, such as citrine (yellow) or prasiolite (green).
Hardness and Durability: On the Mohs scale of mineral hardness, amethyst has a rating of 7. This makes it a relatively durable gemstone, suitable for a variety of jewelry applications, including rings, earrings, and pendants. However, it is not impervious to damage. It can be scratched by substances with a higher hardness, such as corundum (sapphire and ruby, hardness 9) or diamond (hardness 10). It also has fair toughness, meaning it can withstand moderate impact but may cleave or fracture if struck with sufficient force in the right direction.
Clarity and Inclusions: Amethyst is typically found with good clarity, often being eye-clean. Common inclusions can include mineral inclusions, liquid-filled cavities, and growth lines. The presence of these inclusions is natural and can help gemologists distinguish natural from synthetic stones.
Refractive Index and Specific Gravity: Amethyst has a refractive index of approximately 1.544 to 1.553, which is characteristic of quartz. Its specific gravity typically ranges from 2.65 to 2.66. These properties are useful for gemological identification.
Cut and Carat: Amethyst's clarity and color allow it to be cut into a wide variety of shapes and sizes. It is often faceted to maximize its brilliance and color, but it is also commonly carved into beads, cabochons, and ornamental objects. The stone is available in a broad range of carat weights, from small accent stones to large, impressive specimens, making it versatile for different jewelry designs.
