History and Lore
The tradition of assigning gemstones to birth dates has a long and storied history, evolving over centuries across different cultures. For December 19th, the selection of Tanzanite, Turquoise, and Zircon as birthstones reflects a blend of ancient symbolism and modern discovery.
Tanzanite: A Modern Marvel
Tanzanite, a relatively recent addition to the birthstone tradition, was first discovered in 1967 in the foothills of Mount Kilimanjaro in Tanzania. This gemstone quickly gained popularity due to its striking blue-violet color and its unique optical property known as trichroism, where the stone appears to change color when viewed from different angles. Tanzanite’s association with spiritual growth, transformation, and enlightenment has made it a favored stone among those seeking deeper self-awareness and emotional clarity.
Its relatively recent origin contrasts with the ancient histories of other December birthstones, yet its rapid acceptance into the birthstone tradition underscores its symbolic resonance and visual appeal.
Turquoise: A Stone of Protection and Prosperity
Turquoise, one of the oldest known gemstones, has been revered for thousands of years across cultures from ancient Egypt to Native American tribes. Its blue-green hue has long been associated with protection, healing, and good fortune. In many ancient traditions, turquoise was used to create amulets and talismans to ward off evil and ensure safe travel.
For those born on December 19th, turquoise is believed to enhance inner harmony, attract love, and foster a sense of balance. Its historical use in jewelry and spiritual practices highlights its enduring value as both a decorative and symbolic gem.
Zircon: A Dazzling Legacy
Zircon, particularly blue zircon, has a rich geological history and has been used in jewelry for centuries. Known for its brilliance and refractive fire, zircon is often compared to diamonds in its ability to sparkle. The stone has also been associated with positive energy, wisdom, and the power to enhance one’s communication skills.
Zircon’s inclusion as a December 19th birthstone reflects its adaptability and enduring beauty, making it a fitting companion to Tanzanite and Turquoise in representing the diverse qualities of those born on this day.
Geological Formation and Sources
The geological formation of Tanzanite, Turquoise, and Zircon is as fascinating as their histories. Each gemstone is the product of unique geological processes and is found in distinct locations around the world.
Tanzanite: A Unique Geological Phenomenon
Tanzanite is formed under high pressure and temperature conditions and is found only in the Merelani Hills of Tanzania, near Mount Kilimanjaro. Its color is due to the presence of vanadium, and the gem is typically heat-treated to enhance its blue-violet hue. The rarity of Tanzanite is further emphasized by the fact that it is only found in this specific region, making it one of the most exclusive gemstones in the world.
Turquoise: A Product of Copper and Phosphorus
Turquoise is a hydrated phosphate of aluminum and copper, formed through the interaction of copper-rich minerals with phosphorus-bearing solutions. It is commonly found in arid regions where these conditions occur, such as in the southwestern United States, China, and Egypt. Turquoise is often found in veins and nodules within rocks, and its color can vary depending on the presence of other minerals.
The unique blue-green color of turquoise is a result of the copper content in the stone, with higher copper concentration producing a deeper blue. This natural variation has made turquoise a highly valued gemstone in both ancient and modern times.
Zircon: A Durable and Diverse Stone
Zircon is a zirconium silicate mineral that occurs in a wide range of colors, including red, yellow, green, and blue. The blue variety is the most popular in jewelry and is typically heat-treated to enhance its color. Zircon is known for its high refractive index and strong dispersion, giving it a fire and brilliance comparable to diamonds.
Zircon is found in various parts of the world, including Australia, Thailand, and Brazil. Its durability and affordability have made it a popular choice for jewelry, especially as a December birthstone.
