This article delves into the gemstones associated with December 3rd, examining their origins, properties, and cultural significance. We will explore how these stones have been used historically and how they continue to be valued in the modern world of jewelry and gemology.
Historical and Cultural Significance
The Evolution of December’s Birthstones
The tradition of assigning gemstones to specific months of the year has its roots in ancient religious and cultural practices. One of the earliest references to birthstones comes from the biblical Book of Exodus, which describes the twelve gemstones set in the High Priest’s breastplate. However, the specific list of birthstones and their associations with the months of the year has evolved significantly over time.
December's birthstone list has undergone notable changes since the 19th century. In 1870, turquoise was designated as the December birthstone in Tiffany & Co.’s "Gregorian Birthstone Poems." By 1912, the National Association of Jewellers (now Jewellers of America) listed turquoise as the primary December birthstone, with lapis lazuli as an alternative. In 1952, zircon was added to the list by the Jewelry Industry Council of America. Most recently, in 2002, tanzanite was added as a December birthstone, reflecting the ongoing evolution of the tradition.
The inclusion of multiple birthstones for December is a practical as well as symbolic decision. Some sources suggest that this approach allows for a variety of choices in color, price, and personal meaning, catering to different tastes and budgets. For example, while turquoise has long been a traditional choice, tanzanite offers a more modern, vibrant blue-violet hue, and zircon provides a unique range of colors and brilliance.
Turquoise: A Gemstone of Ancient Significance
Among the December birthstones, turquoise has the longest and most well-documented history. The name "turquoise" comes from the French word turquoise, meaning "Turkish," as the gem was once believed to have been brought to Europe from Turkey. However, its origins are much older, with evidence of its use in ancient Egypt, Mesopotamia, and the Americas.
Turquoise has been used for thousands of years, both as a decorative gemstone and as a symbol of protection and good fortune. In ancient Egypt, turquoise was highly valued and was often used in jewelry and amulets. Pharaohs and other rulers adorned themselves with turquoise, believing it to bring health, prosperity, and protection.
In the Americas, turquoise played a significant role in the cultures of the Native American Southwest. It was used in jewelry, carvings, and ceremonial objects, often believed to have spiritual and healing properties. The stone was associated with the sky and the water, symbolizing life and vitality.
Turquoise was also prized in China, where it was carved into intricate objects over 3,000 years ago. Chinese artisans valued its blue-green color and believed it to bring good luck and ward off illness.
Zircon: A Gemstone of Timeless Beauty
Zircon is another gemstone that has been associated with December, particularly in its blue variety. Zircon is an ancient mineral, with some specimens dating back over 4.4 billion years, making it one of the oldest minerals on Earth. This geological significance adds to its appeal as a December birthstone.
Zircon is known for its brilliance and fire, which can rival that of diamonds. It occurs in a wide range of colors, including red, orange, yellow, green, blue, brown, and colorless. The blue variety, known as "blue zircon," is particularly popular as a December birthstone due to its vibrant color and affordability compared to more expensive blue gems like sapphires.
Zircon has also been used in jewelry for centuries. In ancient times, it was often mistaken for other gemstones, including diamonds and emeralds. Its durability and beauty made it a popular choice for rings, pendants, and other fine jewelry pieces.
Zircon is also valued for its metaphysical properties. In some cultures, it is believed to promote clarity of thought, enhance intuition, and protect the wearer from negative energies. These properties make it a meaningful choice for those born in December.
Tanzanite: A Modern Discovery
Tanzanite is the newest of the December birthstones, having been discovered in the 1960s in Tanzania. Named for its place of origin, tanzanite is a relatively rare gemstone that is only found in the area around Mount Kilimanjaro. Its discovery and introduction to the gem market in the 20th century marked a significant moment in the history of December birthstones.
Tanzanite is known for its striking blue-violet color, which can vary depending on the angle at which it is viewed. This color change is due to the way light interacts with the gem’s crystal structure. Tanzanite can range from deep blue to rich purple, and the most valuable specimens display a vivid blue hue.
Tanzanite is also associated with various symbolic meanings. It is believed to promote compassion, peace, and harmony. In some traditions, it is thought to enhance spiritual awareness and encourage emotional healing. These properties make it a meaningful and beautiful choice for December-born individuals.
Geological Formation and Sources
Turquoise: A Product of Arid Environments
Turquoise is a hydrated phosphate of copper and aluminum, with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. It forms in arid environments where copper-rich rocks are exposed to weathering and chemical changes. The process begins when rainwater or melted snow percolates through copper ore deposits, creating an acidic solution that carries copper compounds. This solution then reacts with aluminum and potassium in the surrounding rocks, precipitating turquoise in cavities and cracks.
Turquoise is typically found in weathered volcanic rock and sedimentary rock in arid regions. Major sources of turquoise include the American Southwest (particularly Arizona, New Mexico, and Nevada), as well as Iran, China, and Egypt. Each location produces turquoise with slightly different colors and patterns, depending on the trace elements present in the ore.
One of the unique characteristics of turquoise is its porosity, which makes it susceptible to staining and discoloration. It is also relatively soft, with a hardness of 5–6 on the Mohs scale, making it vulnerable to scratches and damage. To protect turquoise jewelry, it is important to avoid exposure to harsh chemicals, excessive moisture, and extreme temperatures.
Zircon: A Versatile and Durable Gemstone
Zircon is a silicate mineral with the chemical formula ZrSiO₄. It is known for its high refractive index and dispersion, which give it a brilliant, fire-like appearance. Zircon occurs in a wide range of colors, including red, orange, yellow, green, blue, brown, and colorless. The blue variety, known as "blue zircon," is particularly popular as a December birthstone.
Zircon is found in a variety of geological settings, including igneous rocks, metamorphic rocks, and sedimentary deposits. It is often found in alluvial deposits, where it has been eroded from its original rock and transported by water. Major sources of zircon include Australia, India, Brazil, and parts of Southeast Asia.
One of the most remarkable features of zircon is its age. Some zircon crystals have been dated to over 4.4 billion years old, making them among the oldest minerals on Earth. This ancient origin adds to their appeal as a gemstone and as a subject of scientific study.
Zircon is also notable for its durability. It has a hardness of 6.5–7.5 on the Mohs scale, making it more resistant to scratches than turquoise. However, it can be sensitive to heat, and some varieties of zircon may change color or become damaged when exposed to high temperatures.
Tanzanite: A Unique and Rare Gemstone
Tanzanite is a type of zoisite, a calcium aluminum silicate with the chemical formula Ca₂Al₃(SiO₄)(Si₂O₇)O(OH)₃·H₂O. It is known for its vivid blue-violet color, which is caused by trace amounts of vanadium. Tanzanite is only found in a small area near Mount Kilimanjaro in Tanzania, making it one of the rarest gemstones in the world.
The discovery of tanzanite in the 1960s was a significant event in the gemstone world. It was quickly introduced to the market and became popular due to its striking color and rarity. Tanzanite is relatively soft compared to other gemstones, with a hardness of 6–7 on the Mohs scale. It is also sensitive to heat and can lose its color or become damaged if exposed to high temperatures.
Despite its relative softness, tanzanite is a durable and beautiful gemstone that is well-suited for jewelry. Its rarity and unique color make it a valuable and sought-after gemstone, particularly for those born in December.
Gemological Properties
Turquoise: A Soft and Porous Stone
Turquoise is a relatively soft gemstone with a hardness of 5–6 on the Mohs scale. It is also porous, which makes it susceptible to staining and discoloration. The stone is often treated with oils, waxes, or resins to enhance its color and stability. These treatments can also help protect the stone from damage.
Turquoise has a refractive index of 1.61–1.65 and a specific gravity of 2.6–2.8. It is typically opaque or semi-translucent, with a waxy to vitreous luster. The presence of matrix (the rock in which it formed) can affect the appearance of the stone, creating patterns and veins that add to its uniqueness.
Due to its softness and porosity, turquoise requires special care to maintain its beauty and integrity. It should be stored separately from harder gemstones to prevent scratches and should be kept away from harsh chemicals and excessive moisture.
Zircon: A Durable and Brilliant Gemstone
Zircon is a durable and brilliant gemstone with a hardness of 6.5–7.5 on the Mohs scale. It has a high refractive index and dispersion, which give it a fire-like appearance that can rival that of diamonds. Zircon is also known for its pleochroism, meaning it can display different colors when viewed from different angles.
Zircon has a refractive index of 1.78–2.01 and a specific gravity of 3.9–4.7. It is typically transparent to translucent and has a vitreous luster. The stone is often cut into faceted gemstones or cabochons, depending on its color and clarity.
Zircon is a versatile gemstone that can be used in a wide range of jewelry styles. It is particularly well-suited for rings, pendants, and earrings. However, it should be handled with care, as some varieties of zircon can be sensitive to heat and may change color or become damaged when exposed to high temperatures.
Tanzanite: A Rare and Striking Gemstone
Tanzanite is a rare and striking gemstone with a hardness of 6–7 on the Mohs scale. It has a refractive index of 1.694–1.703 and a specific gravity of 3.10–3.38. The stone is typically transparent to translucent and has a vitreous luster.
Tanzanite is known for its pleochroism, which means it can display different colors when viewed from different angles. The most valuable specimens display a vivid blue hue, while others may appear more violet or purple. This color change is due to the way light interacts with the gem’s crystal structure.
Tanzanite is a relatively soft gemstone and should be handled with care. It is sensitive to heat and may lose its color or become damaged when exposed to high temperatures. Tanzanite is also prone to cleavage, meaning it can split along certain planes if struck with force.
