In modern times, Zircon has regained popularity, especially in its blue variety, which is known for its vivid color and affordability. Zircon is believed to carry properties of purification and transformation, making it a suitable stone for individuals undergoing change or seeking clarity in their lives.
Geological Formation and Sources
Tanzanite: A Unique and Limited Resource
Tanzanite is a variety of the mineral zoisite, which is composed of calcium aluminum silicate with traces of vanadium. The blue-violet color of Tanzanite is due to the presence of vanadium and the way the stone absorbs and reflects light. It forms in metamorphic rocks, particularly in areas where high heat and pressure have altered the mineral structure.
Tanzanite is found only in a small region of Tanzania, specifically in the Merelani Hills near Mount Kilimanjaro. This limited geographical distribution makes Tanzanite one of the rarest gemstones in the world. The stone is mined from alluvial deposits and requires careful cutting to enhance its color and clarity.
Turquoise: A Stone of Earth and Sky
Turquoise is a hydrated phosphate of aluminum and copper. It forms in the oxidation zones of copper deposits, where water percolates through the rock and dissolves copper compounds. The presence of copper gives Turquoise its characteristic blue color, while the presence of iron gives it a greenish hue.
Turquoise is found in arid regions where the conditions are suitable for its formation. The most well-known sources of high-quality Turquoise include the United States (especially Arizona and Nevada), Iran, and China. Turquoise from these regions is often prized for its deep blue color and minimal matrix (the dark veins that run through the stone).
Zircon: A Durable and Diverse Gemstone
Zircon is a zirconium silicate that forms in a variety of geological environments, including igneous, metamorphic, and sedimentary rocks. It is known for its high refractive index and dispersion, which give it a brilliant sparkle similar to that of diamonds.
Zircon is found in many parts of the world, including Australia, Brazil, Cambodia, and the United States. The most valuable varieties of Zircon are the blue and colorless types, which are often heat-treated to enhance their color. Zircon is also known for its durability, with a hardness of 6.5 to 7.5 on the Mohs scale.
