Purple amethyst, also known as amethyst, is a stunning variety of quartz that ranges in color from violet to deep purple. As one of the oldest gem minerals recorded, it has held a place of reverence and admiration across various cultures and historical periods. This gemstone, with its enchanting hues and mystical aura, continues to captivate jewelry enthusiasts and collectors worldwide. In this article, we will explore the rarity, characteristics, history, cultural significance, and evaluation criteria of purple amethyst in a detailed and accessible manner.
Characteristics and Composition
Purple amethyst is composed primarily of silicon dioxide (SiO2), with a hardness of 7 on the Mohs scale and a specific gravity of 2.65. Its refractive index ranges between 1.54 and 1.55, exhibiting dichroism, meaning it displays different shades of purple depending on the viewing angle. Natural purple amethyst forms its characteristic purple color due to trace minerals such as iron and manganese. The primary colors include light purple, purple-red, deep red, bright red, deep purple, and blue-purple, with deep purple-red and bright red being the most valued, while lighter shades are considered more common.
Natural purple amethyst often contains natural ice cracks or white cloud-like impurities, adding to its unique charm. This gemstone displays a vitreous luster, which is one of the main bases for identifying and distinguishing it from other similar-looking materials. When viewed under a high-powered magnifying glass, small gas-liquid inclusions and mineral crystal impurities can be seen within the crystal structure of purple amethyst, whereas glass often contains bubbles, which are round or oval in shape.
Formation and Distribution
Purple amethyst primarily forms in sedimentary rocks, such as alluvial deposits, and volcanic rocks, belonging to secondary geological structures. The world’s major deposits of purple amethyst are found in Brazil, Russia, South Africa, Madagascar, Bolivia, Uruguay, Argentina, Zambia, and Namibia. Brazil, known as the “Crystal Country,” accounts for about 90% of the world’s crystal production.
Purple amethyst crystals are often found in volcanic rocks, pegmatites, or crystal cavities within limestone and shale. The scarcity of high-quality purple amethyst crystals, especially those with vibrant colors and minimal impurities, contributes to their rarity and value.
Evaluation Criteria
When assessing the value of purple amethyst, several key factors are considered:
Rarity and Quantity: The rarity of purple amethyst is a crucial factor in determining its value. The fewer pieces available, the higher the perceived rarity and, consequently, the value. Large, high-quality crystals are particularly sought after and command higher prices.
Clarity and Purity: Clarity is another important criterion for evaluating the quality of purple amethyst. For jewelry applications, such as crystal balls and adornments, higher purity translates to higher value. However, for decorative purposes, a certain amount of inclusions can enhance the aesthetic appeal and uniqueness of the gemstone.
Color: The color of purple amethyst is a significant factor influencing its value. Deep, vibrant shades of purple, such as deep purple-red and bright red, are considered the most desirable. The color should be evenly distributed throughout the crystal.
Cut and Craftsmanship: The quality of the cut and craftsmanship can significantly impact the overall appearance and value of purple amethyst. Well-proportioned, skillfully cut, and polished crystals showcase the gemstone’s natural beauty and can enhance its value.
Provenance: The origin of the purple amethyst can also affect its value. Gemstones from certain mines or regions may be more highly valued due to their reputation for producing high-quality crystals.

His tears, resembling wine, turned the statue into a purple gemstone.
