Tanzanite is one of the most mesmerizing gemstones in the world, renowned for its striking blue-violet hues and remarkable rarity. Discovered only in Tanzania, this gemstone has captivated collectors and jewelry enthusiasts alike. A tanzanite gemstone offers a unique blend of beauty, exclusivity, and investment potential. In this guide, we explore what tanzanite is, its value, and why it is considered one of the most sought-after gems.
What is Tanzanite?
Tanzanite is a rare variety of the mineral zoisite, distinguished by its remarkable blue to violet color. First discovered in 1967 near Mount Kilimanjaro, tanzanite gems are found only in one location on Earth, making them incredibly rare. Due to their stunning color and limited supply, tanzanite is considered a modern alternative to traditional gemstones like sapphire.
How Rare is Tanzanite?
Tanzanite is estimated to be 1,000 times rarer than diamonds, as it is sourced from a single location in Tanzania. Experts predict that the known tanzanite deposits may be depleted within a few decades, adding to its exclusivity and potential long-term value. The most prized tanzanites feature a rich, saturated blue-violet color with exceptional transparency. Since large, high-quality tanzanite stones are scarce, their value continues to appreciate over time.
Tanzanite Properties
Tanzanite ranks between 6 and 7 on the Mohs hardness scale, making it softer than sapphires and diamonds. Due to its relative fragility, it requires careful handling and protective settings when used in rings. Despite this, its breathtaking color and rarity make it a prized choice for collectors and jewelry lovers.
Color, Cut, Clarity, and Carat Weight
Color
The most desirable tanzanite gemstones display a rich blue-violet hue with strong saturation. Lighter-colored stones are more common, but deeper shades command higher prices.
Cut
Tanzanite is cut in various shapes, including oval, cushion, and pear, to maximize its pleochroic effect and enhance its brilliance. A well-cut tanzanite showcases its stunning depth of color and sparkle.
Clarity
High-quality tanzanite is typically eye-clean, meaning it has minimal inclusions. Stones with excellent transparency and minimal flaws are considered the most valuable.
Carat Weight
Larger tanzanite stones over 5 carats are rare and highly desirable. Since the gem’s rarity increases with size, tanzanites above 10 carats can command premium prices.
Conclusion
Tanzanite is a truly unique and rare gemstone that continues to gain popularity for its exceptional beauty and exclusivity. As one of the world’s most coveted gemstones, tanzanite remains a stunning choice for fine jewelry collections.
