History and Lore
Turquoise: The Ancient Gem of Protection
Turquoise is one of the oldest known gemstones, with a history that stretches back thousands of years. Archaeological evidence suggests that it was used as early as 3000 BCE by ancient Egyptian, Persian, and Native American cultures. Turquoise was highly valued for its vibrant blue-green color and was often carved into amulets, beads, and talismans. In ancient Egypt, it was associated with the gods and was used in jewelry and decorative objects to symbolize protection and divine favor.
In Native American traditions, particularly among the Navajo, Hopi, and Zuni tribes, turquoise was considered a sacred stone. It was believed to bring good fortune, health, and spiritual protection. Navajo jewelry, in particular, often features turquoise prominently, with the stone being set in silver and used in pendants, rings, and bracelets. The stone's connection to the sky and the earth made it a powerful symbol of balance and harmony.
Tanzanite: The Modern Marvel
Tanzanite is the most recent of the four December birthstones to be discovered and recognized. It was first identified in the 1960s in the foothills of Mount Kilimanjaro in Tanzania, near the city of Arusha. Tanzanite is a relatively new gemstone in the jewelry market, having been introduced to the public in the early 1970s. Its discovery was a significant event in the gemstone world due to its unique color and the fact that it is only found in one location on Earth.
The name "tanzanite" is derived from the country of Tanzania, where the gemstone is exclusively mined. Its deep violet-blue color is due to the presence of trace elements such as vanadium and chromium. Tanzanite's color can vary depending on the lighting, which adds to its allure and mystique. The stone quickly gained popularity for its beauty and rarity, and it was officially recognized as a December birthstone in 2002.
Tanzanite is often associated with transformation, spiritual awakening, and emotional healing. It is believed to enhance intuition and promote a sense of calm and clarity. These metaphysical properties have contributed to its growing popularity in both the jewelry and holistic wellness communities.
Blue Topaz: The Durable Classic
Blue Topaz is a well-known gemstone that has been appreciated for its beauty and durability. While topaz in general has been used in jewelry for centuries, the blue variety is a more recent innovation. Natural blue topaz is extremely rare, and most of the blue topaz available in the market today has been treated to enhance or alter its color. This treatment typically involves irradiation or heat to develop the deep blue hues that make the gemstone so desirable.
Blue Topaz is often associated with clarity of thought, truth, and communication. It is believed to help individuals express themselves more effectively and to bring about a sense of calm and balance. These qualities make it a popular choice for those seeking a gemstone that supports mental and emotional well-being.
The stone's durability, with a hardness of 8 on the Mohs scale, makes it an excellent choice for everyday wear. It is also relatively affordable, which has contributed to its widespread use in jewelry. Blue Topaz is particularly popular in engagement rings and other fine jewelry pieces, where its brilliance and clarity shine.
Zircon: The Sparkling Ancient Stone
Zircon is one of the oldest gemstones, with crystals found in geological formations that date back billions of years. While zircon can occur in a variety of colors, the blue variety is the most popular and is often associated with December birthstones. Blue zircon is created through a heat treatment process that transforms the natural color of the stone into a vibrant blue.
Zircon has a long history of use in jewelry, particularly in ancient cultures such as those in Egypt, India, and Mesopotamia. It was highly valued for its brilliance and was often mistaken for diamonds due to its high refractive index. In medieval Europe, zircon was believed to have protective properties and was used in amulets and talismans to ward off negative energies.
In modern times, zircon is appreciated for its affordability and its ability to mimic the appearance of more expensive gemstones. It is often used in vintage and antique jewelry, where its sparkle and durability make it a desirable choice. Zircon is also associated with wisdom, balance, and spiritual enlightenment, making it a meaningful choice for those born in December.
Geological Formation and Sources
Turquoise
Turquoise is a hydrated phosphate of aluminum and copper, with a chemical formula of Al₂(OH)PO₄. It is typically found in arid regions where copper deposits have been oxidized and reacted with phosphoric acid. This process forms turquoise in the cavities of volcanic rocks and in the oxidation zones of copper deposits. The most famous sources of high-quality turquoise include:
- Iran (Persia): Known for producing the finest quality turquoise with a deep blue color and minimal matrix.
- United States (New Mexico, Arizona, Nevada): Native American tribes in these regions have long mined turquoise for jewelry and ceremonial use.
- China, Russia, and Egypt: These countries also produce turquoise, though the quality varies.
Turquoise is relatively soft, with a hardness of 5–6 on the Mohs scale. It is also porous and can be easily damaged by heat, chemicals, and excessive moisture. This makes it a delicate gemstone that requires special care when set in jewelry.
Tanzanite
Tanzanite is a variety of the mineral zoisite, with a chemical formula of Ca₂Al₃(SiO₄)(OH)₀. The presence of trace elements such as vanadium and chromium is responsible for its distinctive violet-blue color. Tanzanite is only found in one location on Earth—the Merelani Hills in Tanzania, near Mount Kilimanjaro. The deposits are limited, which contributes to the stone's rarity and value.
Tanzanite is relatively soft compared to other gemstones, with a hardness of 6–7 on the Mohs scale. It is also pleochroic, meaning it displays different colors when viewed from different angles. This property is one of the reasons why tanzanite is so unique and desirable in the jewelry market.
Blue Topaz
Topaz is a silicate mineral with a chemical formula of Al₂SiO₄(F,OH)₂. The blue color of topaz is the result of trace amounts of iron and a treatment process that involves irradiation or heat. Natural blue topaz is extremely rare, and most of the blue topaz available in the market is treated to enhance or alter its color.
Blue Topaz is primarily mined in:
- Brazil
- Sri Lanka
- Mexico
- Nigeria
- United States
Blue Topaz is one of the hardest December birthstones, with a hardness of 8 on the Mohs scale. This makes it an excellent choice for everyday wear and for use in engagement rings and other durable jewelry pieces.
Zircon
Zircon is a zirconium silicate with a chemical formula of ZrSiO₄. It occurs in a variety of colors, including colorless, yellow, red, and blue. The blue color is achieved through a heat treatment process that alters the natural color of the stone.
Blue Zircon is typically found in:
- Australia
- Madagascar
- Brazil
- India
Zircon has a hardness of 6–7.5 on the Mohs scale, which makes it relatively durable for jewelry use. It is also known for its high refractive index, which gives it a brilliant sparkle similar to that of a diamond.
