Tanzanite: A Collector's Guide
Tanzanite is a relatively new gemstone, having only been discovered in 1967 in the Merelani Hills of Tanzania. It is a variety of the mineral zoisite, and is prized for its deep blue-violet color. Tanzanite is a relatively hard gemstone, with a Mohs hardness of 6.5, making it suitable for everyday wear.
Color
Tanzanite's most striking feature is its color. The gemstone can range in color from light blue to deep violet, with the most desirable shades being a deep, saturated blue-violet. The color of tanzanite is caused by the presence of vanadium and chromium impurities. When these impurities are heated, they produce the characteristic blue-violet color of tanzanite.
Clarity
Tanzanite is typically found with inclusions, which are tiny flaws or imperfections in the gemstone. These inclusions can be seen with the naked eye, and can range in size from small specks to large, visible crystals. The presence of inclusions can affect the value of a tanzanite gemstone, with cleaner stones being more valuable than those with more inclusions.
Cut
Tanzanite is typically cut into a variety of shapes, including round, oval, cushion, and emerald. The cut of a tanzanite gemstone can affect its appearance and value. Well-cut tanzanites will have a good balance of brilliance and fire, and will show off the gemstone's color to its best advantage.
Carat Weight
Tanzanite is a relatively rare gemstone, and larger stones are more valuable than smaller stones. The carat weight of a tanzanite gemstone is measured in carats, with one carat being equal to 0.2 grams. Tanzanite gemstones can range in size from a fraction of a carat to several carats.
Price
The price of a tanzanite gemstone is determined by a number of factors, including the gemstone's color, clarity, cut, and carat weight. The most valuable tanzanite gemstones are those that have a deep, saturated blue-violet color, are free of inclusions, and are well-cut. Larger tanzanite gemstones are also more valuable than smaller stones.
Caring for Tanzanite
Tanzanite is a relatively delicate gemstone, and should be cared for with care. To clean a tanzanite gemstone, simply use a mild detergent and warm water.
