Turquoise, a captivating gemstone celebrated for its vibrant blue-green hues, holds the distinguished position as the birthstone for December. Revered throughout history for its perceived protective qualities and symbolic representation of enduring love and tranquil energy, turquoise continues to be a popular choice for jewelry, bridging bohemian aesthetics with modern designs. This article delves into the history, geological origins, gemological properties, and care of this timeless gemstone, drawing exclusively from available sources.
History and Lore
The allure of turquoise extends back millennia, with evidence of its use dating to ancient civilizations. Sources indicate that turquoise was highly valued by Egyptian pharaohs, signifying power and protection. Its historical significance is further underscored by its prominent role in the traditions of Native American cultures, where it was considered a sacred stone embodying balance and well-being.
The gemstone’s journey to becoming a modern birthstone is rooted in its long-standing cultural importance. While specific dates regarding its formal designation as the December birthstone are not provided in the available sources, its consistent association with the month through tradition and modern jewelry practices solidifies its position. Today, turquoise remains a symbol of good fortune and positive energy, frequently incorporated into jewelry as a personal talisman.
Geological Formation and Sources
Turquoise is not formed in magma or deep within the Earth’s crust, but rather in relatively shallow deposits. Its formation occurs through a chemical reaction involving copper, aluminum, and phosphorus, along with water, in arid regions. This process typically takes place in the presence of volcanic rock.
The sources indicate that turquoise is mined globally, with notable deposits found in Iran, Egypt, the United States, and China. Each location yields turquoise with unique characteristics, contributing to the gemstone’s diverse range of colors and patterns. The sources do not provide specific details regarding the geological conditions of each location, but highlight the widespread availability of this gemstone.
Gemological Properties
Turquoise is characterized by its distinctive color, ranging from sky blue to greenish-blue, often with veining or matrix patterns. The sources do not provide a specific chemical formula or refractive index for turquoise. However, they emphasize its natural origin and the importance of ethically sourcing the gemstone.
The available sources detail several physical characteristics relevant to jewelry making and care:
- Material: Typically set in sterling silver (925) or 18 karat gold vermeil.
- Hardness: While a specific Mohs hardness scale rating is not provided, the sources suggest caution during wear, advising against exposure to harsh chemicals or abrasive activities.
- Size: Pendant gemstones can measure approximately 17mm x 8mm with a thickness of 4mm, or around 2.5mm for petite designs.
- Cut & Shape: Commonly found as round cabochons or marquise shapes, often bezel set with silver granules.
The sources also highlight the porous nature of turquoise, which requires specific care to maintain its beauty.
Symbolism and Metaphysical Beliefs
Throughout history, turquoise has been imbued with symbolic meaning. As noted previously, it represents power, protection, and balance. More recently, it is associated with tranquil energy and enduring love. The sources do not elaborate on specific metaphysical beliefs beyond these general associations. However, the continued use of turquoise in jewelry suggests a persistent belief in its positive influence.
Care and Cleaning
Due to its porous nature, turquoise requires gentle care to prevent discoloration or damage. The sources consistently advise against exposure to harsh chemicals, soaps, or perfumes. Cleaning should be limited to wiping with a dry or slightly damp cloth. The use of water or cleaning products is strongly discouraged.
Proper storage is also crucial. The sources recommend storing turquoise jewelry in a microsuede pouch to protect it from daily exposure to elements that can cause tarnishing or damage. It is important to ensure the jewelry is completely dry before storage.

The sources feature examples of turquoise pendants crafted in 18 karat gold vermeil and sterling silver, often incorporating delicate chains and minimalist settings. Turquoise is frequently presented as a birthstone pendant, offering a personalized and meaningful gift.
