Together, these stones offer a rich tapestry of meaning and beauty, making December a particularly unique month in the birthstone tradition.
History and Lore
Turquoise: The Stone of Protection and Royalty
Turquoise has been revered for thousands of years and is considered one of the oldest known gemstones. Its use dates back to ancient Egypt, where it was used in jewelry and amulets. In ancient times, turquoise was believed to offer protection, prosperity, and even divine favor. Shamans and spiritual leaders in various cultures used turquoise as a talisman, believing it could ward off negative energies and attract good fortune.
In medieval times, turquoise became a symbol of royalty and nobility. It was often set in gold and worn by monarchs as a sign of wealth and power. In the East, particularly in China and Persia, turquoise was highly prized and used in intricate inlays in furniture and decorative objects. This tradition of using turquoise for both aesthetic and symbolic purposes has continued into the modern era.
Turquoise is also associated with the zodiac sign Sagittarius, which spans part of December. Those born under this sign are said to benefit from turquoise's properties of protection and emotional stability.
Zircon: The Silent Healer
Zircon is a lesser-known but equally fascinating birthstone for December. While it was not officially recognized as a birthstone until after 1952, it has been used in jewelry and spiritual practices for centuries. Zircon is known for its quiet energy and is often associated with emotional balance and joy.
Blue zircon, in particular, is the most commonly associated with December and is valued for its brilliance and clarity. It is believed to bring a sense of calm and clarity to the wearer, helping to dispel negative emotions and promote a more positive outlook. This makes it a popular choice for meditation and spiritual practices.
Before zircon became a recognized December birthstone, lapis lazuli held that position. Lapis lazuli was once a stone of ancient royalty and artists, used in jewelry, art, and even as a pigment in paintings. It was believed to bring wisdom, truth, and inner peace. While lapis lazuli is no longer officially listed as a December birthstone, it is still considered a traditional alternative.
Tanzanite: The Modern Discovery
Tanzanite is the youngest of December’s birthstones, having been officially recognized in the United States in 2002. It was discovered in 1967 in the foothills of Mount Kilimanjaro in Tanzania. This gemstone is unique in that it is only found in this specific location, making it one of the rarest gemstones in the world.
Tanzanite is known for its deep blue to violet color, which can vary depending on the angle of light. It is a protective and soothing stone that is said to help the wearer communicate spiritual insights with clarity and calmness. Its recent addition to the December birthstone list reflects the evolving nature of the birthstone tradition, which now includes more modern discoveries.
Blue Topaz: A Stone of Clarity and Wisdom
Blue topaz is another modern addition to the December birthstone list and is often considered the Hindu birthstone for the month. It is a soft and gentle gemstone that is believed to stimulate self-esteem and the ability to learn. It is also associated with emotional calmness and spiritual alignment.
In ancient times, topaz was thought to have healing properties and was used to ward off illness and bring good fortune. It is also believed to help clear the mind and enhance intuition. For those born in December, blue topaz can be a powerful tool for emotional balance and intellectual clarity.
Geological Formation and Sources
Turquoise: The Product of Arid Environments
Turquoise is a hydrated phosphate of aluminum and copper, with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. It forms in arid environments, typically in the weathered oxidation zones of copper deposits. The process involves rainwater or melted snow percolating through copper ore deposits, creating an acidic solution that reacts with aluminum and potassium in the rocks to form turquoise.
This gemstone is found in a variety of countries, including the United States (particularly in the Southwest), Egypt, China, and Iran. Turquoise is often found in cavities and fissures in volcanic and sedimentary rocks. It is known for its porous nature and can easily absorb oils, lotions, and other substances, which can change its color over time.
Turquoise has a relatively low hardness on the Mohs scale, ranging from 5 to 6. This means it can be easily scratched or damaged if not handled properly. To preserve its color and luster, it should be kept away from harsh chemicals and stored separately from harder gemstones.
Zircon: A Versatile and Durable Gemstone
Zircon is a zirconium silicate with the chemical formula ZrSiO₄. It is known for its high refractive index and dispersion, which gives it a brilliant and fire-like appearance. Zircon can occur in a range of colors, including blue, yellow, brown, and colorless, though the blue variety is most commonly associated with December.
Zircon is found in a variety of geological settings, including metamorphic and igneous rocks. It is known for its durability, with a hardness of 6.5 to 7.5 on the Mohs scale. This makes it a suitable gemstone for everyday wear, though it should still be handled with care to avoid damage.
Zircon is found in countries such as Australia, Brazil, and the United States. It is often heat-treated to enhance its color, particularly for the blue variety, which is the most popular in jewelry.
Tanzanite: A Unique and Rare Discovery
Tanzanite is a relatively recent discovery in the world of gemstones. It was first identified in 1967 in Tanzania, near the base of Mount Kilimanjaro. It is a trichromatic gemstone, meaning it can exhibit three colors—blue, purple, and green—depending on the angle of light.
Tanzanite is a type of zoisite that has been heat-treated to enhance its color. Its chemical formula is Ca₂Al₃(SiO₄)(Si₂O₇)O(OH). Tanzanite has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable but still requiring care to avoid scratches and other damage.
Because tanzanite is found only in Tanzania, it is considered one of the rarest gemstones in the world. Its unique color and limited availability have made it highly sought after in the jewelry industry.
Blue Topaz: A Versatile and Popular Gemstone
Blue topaz is a silicate of aluminum and fluorine, with the chemical formula Al₂(SiO₄)(F,OH)₂. It is a relatively hard gemstone, with a hardness of 6 to 6.5 on the Mohs scale. It is known for its gentle blue color and is often used in jewelry for its durability and affordability.
Blue topaz is found in various parts of the world, including Brazil, the United States, and Nigeria. It is often heat-treated or irradiated to enhance its color. The blue variety is the most popular in December jewelry, as it is associated with emotional clarity and spiritual alignment.
