Speaking of tanzanite, few people can recognize it. But when it comes to the huge jewel "The Heart of the Sea" in the movie "Titanic", I believe many people will know it. "The Heart of the Sea" is a tanzanite weighing more than 40 carats. Although Tanzanite has entered the circle of middle and high-end jewellery for more than 40 years, there are very few people who have heard of tanzanite in China. Most of the time, this blue and brilliant gemstone is always mistaken for sapphire. Compared to the increasingly rare and expensive sapphire, the price of tanzanite is more intimate. Tanzanite is not well-known in China, but we look at many international jewellery brands, all of which regard Tanzanite as the darling. Can Tanzanite in China also take the path of rapid popularity like diamonds? The mineral name of tanzanite is called zoisite. No gem-grade zoisite has ever been found before. The zoisite has always been regarded as a mineral. It was not until the 1960s that gem-quality zoisites were found in Tanzania, which were crystal clear and could be used to process jewellery. In order to commemorate this newly republic, the gem-grade zoisite was named tanzanite. The color of tanzanite is mainly blue, with trichromaticity. It looks different in color and shade from different directions. In addition, its refractive index is also relatively high, and its high refractive index determines its surface gloss is relatively strong. Tanzanite has been in existence for more than 40 years, but it has been popular for a few years. As a kind of gem, if you want to be in the mainstream, the beautiful appearance is not enough, you need to have a certain output support. Just like gold emeralds, although it is one of the five precious gemstones, it has not become a mainstream gem because of too little production. Tanzanite's production in recent years has been relatively large, and it has gradually been recognized by the public. In the Guangzhou market, tanzanite is still rare today, is it because its market recognition is not high? As early as a few years ago, Guangdong Geological Bureau Guangdi Jewelry Co., Ltd. was optimistic about the prospects of tanzanite. The earliest introduction of tanzanite in Guangzhou, although the price has indeed increased several times in recent years, compared to other gemstones, because of The dark blue of mulberry is not liked by most Chinese people, and it is contrary to the national colors such as red and golden, so the increase is not too big. However, with the rise of colored gemstones in recent years, it is believed that the market acceptance of tanzanite will be higher and higher. Because its price is relatively low compared to its quality, we all say that it is a newcomer to the gem world. Because there are not many people in China who know Tanzanite, Tanzanite is often mistaken for sapphire. How should we distinguish them? First, tanzanite is much cheaper than sapphire; secondly, tanzanite is more colorful than sapphire. Most sapphires are grayish or blackish, while tanzanite is more blue; third, tanzanite is more "big" than sapphire, and 1-2 carats of sapphire are relatively large. Tanzanite has more than a dozen carats; fourth, most of the tanzanites are relatively clean and clear, and the impurities of sapphire are relatively more. Of course, tanzanite is also not as good as sapphire, that is, the ordinary people are not high enough to recognize it. This is because Tanzanite was discovered late, and historical accumulation and cultural accumulation are not enough. There are many famous sapphire stones in history, and Tanzanite has no famous stones except the promotion of Titanic. In addition, tanzanite is not only similar to sapphire, but also difficult to distinguish from cordierite and kyanite from the naked eye. If it is processed into a ring face, it is more difficult to identify. The most scientific methods of identification are to send them to a specialized testing agency for testing. By measuring the hard indicators such as density and refractive index, the real identity can be identified at once. What is the future trend of tanzanite? The price of tanzanite has risen and it has been a matter of the past five years and is still in its infancy. It is expected that the price of tanzanite will increase every year for the next ten years and eight years. Large-grain, high-quality tanzanite is a collection-grade gemstone, and the price increase may be even larger; the average quality of tanzanite may be less. If you are interested in investing in jewelry, tanzanite is also a good choice.
