History and Lore
The tradition of associating gemstones with the months of the year has roots in ancient cultures. In the Gregorian calendar, as well as in older systems such as the Tibetan and Indian calendars, December is represented by multiple stones, each with its own story.
Turquoise: The Ancient Protector
Turquoise is perhaps the most ancient of December’s birthstones. It has been revered for thousands of years across various civilizations, including the Egyptians, Persians, and Native Americans. In ancient Egypt, turquoise was considered a symbol of life, protection, and divine favor. Pharaohs and high priests often wore turquoise to ward off evil and ensure safe passage in the afterlife.
In the Middle East and Asia, turquoise was believed to possess healing properties and was used to treat ailments ranging from fevers to mental fatigue. The stone was also associated with good luck and prosperity, especially in times of war or political unrest.
Tanzanite: The Modern Marvel
Tanzanite is a relatively new addition to the birthstone list, first discovered in 1967 in Tanzania. It was created through a unique geological process involving the transformation of zoisite under high heat and pressure. Tanzanite’s deep blue-violet color was achieved through heat treatment, which enhanced its natural beauty and made it suitable for jewelry.
Unlike the ancient turquoise, tanzanite is a modern gemstone that quickly gained popularity due to its rarity and vibrant color. It has since become a symbol of transformation, intuition, and spiritual growth, making it a meaningful choice for those born in December.
Blue Topaz: The Sparkling Classic
Blue topaz has long been admired for its brilliant blue color and clarity. In the 20th century, blue topaz was designated as the primary December birthstone in the United States, largely due to its availability and affordability. It is one of the most popular gemstones in the world, used in a wide range of jewelry designs.
Historically, topaz was believed to have protective powers and was worn by warriors and travelers to shield them from harm. The ancient Greeks associated topaz with strength and courage, and it was even thought to have the power to ward off nightmares and bring peace of mind.
Zircon: The Underappreciated Gem
Zircon, another December birthstone, is often overlooked but deserves attention for its rich color and historical significance. Zircon comes in a variety of colors, including blue, red, and golden, with the blue variety being the most popular for December. Unlike turquoise or topaz, zircon has a high refractive index, giving it a sparkling, glass-like appearance.
Zircon has been used in jewelry for centuries, particularly in antique and vintage pieces. It was once a popular substitute for diamonds due to its brilliance and fire. In some cultures, zircon was believed to bring good fortune and wisdom, and it was often carried as a protective talisman.
Geological Formation and Sources
Understanding the geological origins of December’s birthstones helps explain their rarity, color, and value. Each of these gemstones is formed through unique processes and is found in specific regions around the world.
Turquoise: A Product of Arid Environments
Turquoise is formed through the interaction of copper and phosphorus-rich minerals in arid regions. It typically occurs in limestone deposits that have been exposed to weathering and chemical changes over time. The presence of copper gives turquoise its blue color, while iron contributes to its green hues.
Significant sources of turquoise include:
- United States (Arizona, New Mexico, Nevada)
- Iran
- Egypt
- China
- Mexico
- Central Asia and Africa
Turquoise is often found in matrix form, meaning it is embedded in the rock from which it formed. This gives the stone its unique spiderweb-like appearance, which is considered highly desirable in jewelry and decorative objects.
Tanzanite: A One-of-a-Kind Stone
Tanzanite is an exceptionally rare gemstone, found only in Tanzania, where it was discovered in 1967. It is a metamorphic gemstone, meaning it was formed through the transformation of zoisite under extreme heat and pressure. The blue-violet color of tanzanite is the result of traces of vanadium and iron in the crystal structure.
Tanzanite is mined in the Merelani Hills near Arusha, Tanzania. Due to its limited geographic source, tanzanite is considered a once-in-a-lifetime gem and is expected to become even rarer over time.
Blue Topaz: A Versatile and Affordable Gem
Blue topaz is a silicate mineral that occurs naturally in a colorless or pale yellow form. The deep blue color associated with December’s blue topaz is the result of heat treatment and irradiation, which enhances the stone’s natural properties.
Blue topaz is widely available and is found in several countries, including:
- Brazil
- United States
- Nigeria
- Russia
- Australia
Its affordability and durability (it ranks 8 on the Mohs scale) make it a popular choice for everyday jewelry.
Zircon: A Durable and Lustrous Stone
Zircon is a zirconium silicate mineral that occurs in a variety of colors, including blue, red, green, and golden. The blue zircon used as a December birthstone is typically heat-treated to enhance its color.
Zircon is found in a number of countries, including:
- Zimbabwe
- Sri Lanka
- Myanmar (Burma)
- Australia
- India
Zircon is known for its high refractive index, which gives it a sparkling, glass-like appearance. It is also very durable and ranks 7.5 to 8 on the Mohs scale, making it suitable for everyday wear.
