December boasts not one, but two traditional birthstones: blue topaz and turquoise. Both gems are celebrated for their captivating blue hues, symbolizing honor, trust, prosperity, and wisdom. These stones have a rich history, adorning artifacts from ancient civilizations and continuing to grace modern jewelry designs. This article will delve into the history, geological origins, gemological properties, symbolism, and care of these remarkable December birthstones.
History and Lore
Turquoise holds a particularly ancient significance, having been honored by humankind for millennia. Evidence of its use dates back to ancient Egypt, where it was found embedded in the adornments of mummies, and in Mesoamerican cultures, where it featured prominently in masks and ceremonial objects. Beyond its aesthetic appeal, turquoise has long been considered a protective stone, believed to ward off negative energy and connect the wearer to the earth.
Blue topaz also possesses a storied past. In the Middle Ages, it was thought to possess healing properties, capable of alleviating mental disorders and even preventing death. Egyptians utilized topaz as an amulet, believing it offered protection against injury. More recently, blue topaz has been associated with faithfulness and eternal love. Both stones continue to be incorporated into contemporary jewelry, including Celtic designs, demonstrating their enduring appeal.
Geological Formation and Sources
Blue topaz is a silicate mineral composed of aluminum and fluorine, with a chemical formula of Al2SiO4(F,OH)2. Naturally occurring blue topaz is relatively rare. Significant deposits are found in the Ural Mountains of Russia, Brazil, Pakistan, Zimbabwe, and even Mason County, Texas, where it is designated as the state gemstone. However, the majority of blue topaz available commercially originates from Brazil.
Turquoise, conversely, derives its varied blue and green colors from copper minerals present during its formation. It exhibits over twenty color variations. The sources for turquoise are not detailed in the provided materials beyond a general statement of its ancient use in Egypt and Mesoamerica.
Gemological Properties
Blue topaz registers an 8 on the Mohs hardness scale, indicating excellent durability and making it suitable for carving and jewelry. It exhibits a glass-like luster and can range in transparency from transparent to opaque. The color of blue topaz varies considerably, from very pale to a deep, inky blue. The darker shades are typically achieved through heat treatment. Blue topaz crystallizes in the Orthorhombic Crystal System. It also exhibits perfect cleavage, contributing to its brittleness and susceptibility to scratches.
Turquoise is described as a grounding stone, connecting the wearer to the earth. The provided materials do not specify its hardness or chemical composition.
Several varieties of blue topaz are distinguished by their color:
- London Blue Topaz: Characterized by a deep, inky blue color, highly prized by collectors.
- Swiss Blue Topaz: Displays a vibrant, medium-light blue hue.
- Sky Blue Topaz: Offers a light, aqua-colored appearance.
Symbolism and Metaphysical Beliefs
Blue topaz is often referred to as the “clarity stone,” believed to stimulate open communication and encourage positive action. It symbolizes opportunity, possibility, and deep, honest feelings. It is also associated with wisdom and success, and is thought to redirect positive energies where they are most needed. Traditional beliefs attribute to blue topaz the ability to relieve stress, ease migraines, soothe sore throats, and alleviate body aches. When worn near the throat, it is said to provide relief from throat-related ailments.
Turquoise is traditionally viewed as a protection stone, offering energetic benefits and a youthful vibrancy to any fashion. It is believed to provide great energy and is often worn by travelers for protection.
Care and Cleaning
Due to its hardness of 8 on the Mohs scale, blue topaz is relatively durable. However, its brittleness and perfect cleavage necessitate careful handling, particularly when set in jewelry prone to impact. Regular cleaning can be performed with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals.
