Tanzanite: A Collector's Gemstone
Tanzanite is a relatively rare gemstone that is found in only one place on Earth: the Merelani Hills of Tanzania. This beautiful blue-violet mineral is a type of zoisite, and it is prized by collectors for its unique color and crystal structure.
Color and Clarity
Tanzanite is typically a deep blue-violet color, but it can also be found in shades of purple, green, and brown. The color of tanzanite is caused by the presence of vanadium and chromium impurities. The most valuable tanzanite stones are those that have a deep, saturated blue-violet color and are free of inclusions.
Crystal Structure
Tanzanite crystals are typically long and prismatic, with a hexagonal cross-section. They can range in size from a few millimeters to several centimeters. Tanzanite crystals are often twinned, which means that they are made up of two or more crystals that are joined together. This twinning can create interesting patterns and colors in the stone.
Mohs Hardness
Tanzanite has a Mohs hardness of 6.5, which means that it is relatively hard and durable. However, it is still important to take care when handling tanzanite jewelry, as it can be scratched or chipped if it is dropped or knocked against a hard surface.
Care and Cleaning
Tanzanite should be cleaned with a mild detergent and warm water. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone. Tanzanite should also be stored in a cool, dark place, as exposure to light can cause the color to fade.
Tanzanite Jewelry
Tanzanite is a beautiful and versatile gemstone that can be used in a variety of jewelry designs. It is often used in rings, necklaces, earrings, and bracelets. Tanzanite can also be used in combination with other gemstones, such as diamonds, sapphires, and rubies.
Conclusion
Tanzanite is a truly unique and special gemstone that is sure to please any collector. Its beautiful color, clarity, and crystal structure make it a valuable addition to any jewelry collection.
