Purple birthstones hold a unique place in the world of gemology, admired for their regal hues and rich symbolism. These gemstones, ranging from the delicate lilac of kunzite to the deep royal purple of amethyst, have long been associated with nobility, wisdom, and spiritual insight. As birthstones for several months of the year, they are not only treasured for their aesthetic beauty but also for their historical and cultural significance. This article explores the most notable purple birthstones, their gemological properties, their origins, and the meanings attributed to them across different eras and cultures.
History and Lore
The history of purple birthstones is intertwined with centuries of human fascination with the color purple. Historically, purple has been reserved for royalty and the elite due to the rarity and expense of purple dyes in ancient times. This association with power and prestige extended to gemstones, making purple stones highly coveted throughout history.
Amethyst, the most well-known of the purple birthstones, was particularly revered in ancient civilizations. The name amethyst is derived from the Greek word “amethystos,” meaning “not intoxicated,” a reference to the belief that the gemstone could protect against the effects of alcohol. In ancient Greece and Rome, amethyst was often used in drinking vessels and carried as a talisman by those who wished to remain sober. The belief in its protective and calming properties has persisted through the ages, and today amethyst is still associated with mental clarity, emotional balance, and spiritual growth.
In Christian tradition, purple is one of the canonical colors used in religious ceremonies, symbolizing humility and purification. The color is also linked to the biblical high priest's breastplate, which is said to have included a ninth gemstone believed to be of a violet hue. This religious significance added to the mystique of purple gemstones and contributed to their enduring popularity.
In the 19th and 20th centuries, the use of purple gemstones in jewelry became more widespread, thanks to advancements in mining and gem cutting techniques. Amethyst, in particular, became a staple in Victorian jewelry, often set in silver and used in brooches, rings, and pendants. The gemstone's affordability and beauty made it accessible to a broader audience, solidifying its status as a beloved birthstone.
Other purple gemstones, such as tanzanite and kunzite, gained popularity in the modern era. Tanzanite, discovered in Tanzania in the 1960s, quickly became a favorite for its striking color and rarity. Kunzite, while not traditionally a birthstone, is often used in alternative birthstone lists and is prized for its soft, soothing hues and its association with emotional healing and serenity.
Geological Formation and Sources
The geological formation of purple gemstones is as diverse as the stones themselves. Amethyst, a type of quartz, forms in geodes and rock cavities where silica-rich water deposits crystallize over time. The purple color of amethyst is due to the presence of iron impurities and natural irradiation, which create a complex lattice that gives the stone its distinctive hue. Amethyst is found in various locations around the world, including Brazil, Uruguay, Russia, and the United States. Brazil, in particular, is known for producing some of the finest and most vibrant amethyst in the world.
Tanzanite, on the other hand, is a relatively new gemstone that was first discovered in Tanzania in 1967. It is a variety of the mineral zoisite and is only found in a small area near Mount Kilimanjaro. The stone's unique color, which can range from deep blue to rich purple depending on the angle of light, is due to the presence of vanadium and the way it interacts with radiation. Tanzanite's rarity and beauty have made it a highly sought-after gemstone, and it is often considered a luxury item in the jewelry market.
Kunzite is a member of the pyroxene mineral family and forms in granitic pegmatites, where it crystallizes under high temperatures and pressures. The stone's purple color is caused by the presence of manganese, and its soft, delicate hues are often enhanced by heat treatment to improve color uniformity. Kunzite is primarily found in Brazil, Afghanistan, and the United States, with Brazil being the largest producer. The gemstone is known for its clarity and brilliance, making it a popular choice for jewelry despite its relatively low hardness compared to other gemstones.
Purple tourmaline, also known as lilac tourmaline or rubellite, is another gemstone with a rich geological history. It is a type of tourmaline that forms in metamorphic and igneous rocks and is known for its pleochroism, which means it can display different colors when viewed from different angles. Purple tourmaline is primarily found in Brazil, Sri Lanka, and Africa, and its color is due to the presence of iron and manganese. The gemstone is highly valued for its vibrant color and durability, making it suitable for a wide range of jewelry applications.

Care and Cleaning
Proper care is essential to maintain the beauty and longevity of purple birthstones.
