History and Lore
The Ancient Significance of Turquoise
Turquoise has a long and storied history, dating back to ancient civilizations such as the Egyptians, Chinese, and Native Americans. The stone's blue-green color was often associated with the divine and the natural world, and it was believed to possess protective and healing properties.
In ancient Egypt, turquoise was used in jewelry and amulets to ward off evil and bring good fortune. It was also used in decorative arts, including inlays in furniture and ceremonial objects. The Egyptians considered turquoise a symbol of life and immortality, and it was often buried with the deceased to ensure their safe passage to the afterlife.
In Native American cultures, particularly among the Navajo and Hopi tribes, turquoise was believed to be a sacred stone with powerful spiritual properties. It was used in jewelry and ceremonial objects to connect with the natural world and to promote healing, protection, and prosperity.
Tanzanite: A Modern Discovery
Tanzanite is a relatively recent addition to the world of gemstones. Discovered in 1967 in the Merelani Hills of Tanzania, it was named after the country in which it was found. The stone quickly gained popularity due to its striking blue-purple color and its rarity.
Tanzanite was marketed as the "December birthstone" in the 1970s, and it has since become a popular choice for jewelry. Its discovery and commercialization were carefully managed to ensure its value and exclusivity. Unlike many other gemstones, tanzanite is only found in one location in the world, making it one of the rarest and most valuable gemstones on the market.
Zircon: An Ancient Gem with a Modern Appeal
Zircon is an ancient gemstone that has been used for thousands of years. It has been found in archaeological sites dating back to 600 BCE, and it was highly valued in ancient civilizations for its brilliance and durability. Zircon is often mistaken for other gemstones such as diamonds and cubic zirconia due to its high refractive index and dispersion.
Zircon comes in a variety of colors, including colorless, yellow, red, and blue. The blue variety, known as "star blue zircon," is particularly popular and is often used in jewelry. Zircon was once considered a diamond substitute due to its brilliance, and it was a common choice for rings and other fine jewelry pieces in the 18th and 19th centuries.
Geological Formation and Sources
Turquoise: A Product of Nature's Alchemy
Turquoise is a hydrated phosphate of aluminum and copper. It is formed when acidic groundwater interacts with minerals containing aluminum and phosphorus, leading to the creation of the blue-green gemstone. The presence of copper gives turquoise its characteristic blue color, while iron impurities result in green tones.
Turquoise is typically found in arid regions where there is a high concentration of copper deposits. Major sources of turquoise include:
- United States – particularly in Arizona, New Mexico, and Nevada
- Iran – historically known for producing high-quality turquoise
- China – a significant source of turquoise, especially in the Xinjiang region
- Mongolia – known for its rich turquoise deposits
Each of these sources produces turquoise with unique characteristics, and the quality of the stone is often determined by its color, hardness, and the presence of matrix (the host rock that is sometimes left in the stone).
Tanzanite: A One-of-a-Kind Gem
Tanzanite is a variety of the mineral zoisite, and it is known for its pleochroism, which means that it displays different colors when viewed from different angles. The most desirable color of tanzanite is a deep blue-violet, which is the result of trace amounts of vanadium in the stone.
Tanzanite is found only in the Merelani Hills in Tanzania, which is located near the city of Arusha. The area was once a volcanic region, and the unique geological conditions that exist there are responsible for the formation of tanzanite. The stone is mined from alluvial deposits, and the mining process is carefully regulated to ensure the sustainability of the resource.
Zircon: A Durable and Diverse Gem
Zircon is a silicate mineral that is found in a variety of geological settings. It is often found in metamorphic and igneous rocks, and it is known for its resistance to weathering and erosion. Zircon is one of the oldest minerals on Earth, with some crystals dating back over 4 billion years.
The different colors of zircon are the result of impurities in the crystal structure. For example, the blue color of star blue zircon is the result of heat treatment. Zircon is found in a number of countries, including:
- Australia – a major source of zircon, especially the colorless and yellow varieties
- Brazil – known for producing high-quality red and yellow zircons
- India – a significant source of zircon, particularly in the state of Andhra Pradesh
- Madagascar – known for producing a wide range of zircon colors
Zircon is often heat-treated to enhance its color, and the resulting stones are highly valued in the jewelry industry.
