Tanzanite is one of the premier gemstones in the world. Its mineralogical name is “blue zoisite”, mineral with blue color. When Tiffany & Co became the main distributors, they named this gem-quality mineral by the world’s only known deposit in Tanzania, Africa. This gorgeous blue gem with high clarity is very rare, in fact, it is 1000 times rarer than the diamond. It is excavated in an area of only a few square miles on the slopes of mount Kilimanjaro. It is estimated that the supply remaining in the mine will only last for about 30 years. Because of that, Tanzanite becomes more precious every day.
Its exquisite color is a mixture of violet to purple and pure blue. This color combination, similar to that of a fine sapphire makes the Tanzanite unique and instantly popular among gemstones.
Surprisingly, considering the relatively recent discovery, it is among the top ten best-selling gemstones in the jewelry market today.
In order to purchase Tanzanite in a more informed style, you need to understand the qualities and properties of the gem. The Tanzanite, similar as with diamonds, is graded according to the four C’s; Color, Clarity, Cut, and Carat Weight. So before buying your Tanzanite, you need to check all 4 C’s . The higher the combination, the more valuable the stone is.
The Intensity of color and its saturation is very important. The depth ranges from exceptional in larger stones to somewhat pale in smaller ones. Deeper color means better, bigger and rarer stone.
Clarity means that the gem doesn’t have any natural flaws and inclusions. The clarity can extend from “eye clean”, slightly included”, “moderately included” and “heavily included”. Les flaws it has, the more valuable it is.
Cut refers to the stone’s brilliance, the proportions, and the finish. Excellent cut ensures that the stone brilliantly reflects light to ensure maximum satisfaction. So the better the craftsman is and the more precise cutting he makes, the more valuable the stone will be.
Carat is a weight measurement, equivalent to 1/5th of a gram and has 100 points. What’s interesting is that the Tanzanite stones have different Carat Weights when they vary in depth.
The price history of Tanzanite has been unstable. Since its discovery in the 1960s, it has seen many rises and falls. These changes are mainly related to the limited number of mines and resources. Also, the Tanzanian government with its regulations often have an instantaneous impact on the supply, availability, and price. Illegal mining and smuggling, mining challenges or even the natural events like floods also have an effect on the price.
When prices change, top quality stones in larger sizes, are very rare to find. They tend to increase their value in rising markets while retaining it in down markets.
Dark blue color stones are valued higher than those with more violet. Medium dark colors are considered ideal. Larger quality stones are rising in price and rapidly decreasing in availability these days.
The most available sizes for purchase in the jewellery markets are those below 20 carats.The price for fine quality Tanzanite that “holds” more color in the 3 to 5 carat range is approximate $500 to $1000 per carat or more.
The rising demand for Tanzanite means that possibility of doubling or even maybe tripling of the value over the next several years is very real, so if you are under the spell of this majestic gem, now is the perfect time to place an order.
