Tiffany & Co. officially brought Tanzanite to the international gem market in 1968, and this year is the 50th anniversary. In 1967, members of the Marseille tribe in the northern part of Tanzania discovered a cluster of crystals that were highlighted by the weathering of the soil. They were highly transparent and showed a vivid purple-blue color. He reminded the local treasure hunter named Manuel d’Souza that he quickly registered four mining rights. Soon after, Campbell Bridges, the Saffron discoverer, brought this purple-blue gem to the Western world. Tiffany recognizes the potential of this gemstone as an international bestseller and has reached an agreement to become its main distributor. Thus, Tiffany named the gem in his country of origin and launched a large-scale publicity in 1968. Almost overnight, Tanzanite has been hailed by top jewellery designers and other gem professionals, as well as customers who appreciate the beauty and extraordinary personalized couples jewelry.
Today, Tanzanite, which has a good color and interesting story, has become one of the most popular gemstones in the world. In 2002, it joined the birthstone list as the birthstone of December. The foothills of Kilimanjaro National Park are still the only places where they are mined. Like other colored stones, the brightly colored Tanzanite is very popular. Compared with Tanzanite stone, which has bright colors and subtle appeal, the number of Tanzanite stones with lighter colors and softer colors is more and the price is cheaper. Then the question is coming. How do you evaluate them when you buy tanzanite? Of course still – 4C standard.
01 Tanzanite hue and saturation classification 1. GIA divides the tone Tone into 10 levels and the saturation degree is divided into 6 levels. 2, tanzanite has pleochroism, usually blue and purple. V=Violet (purple) B= Blue (blue) Uppercase B and V represent the main color, vB is the main color of blue, and bV is the main color of purple. 3, GIA believes that the color of bV 6/5 or vB 6/5 is the best, bV, vB represents color, 6 represents the tone, and 5 represents the saturation. Other grading standards may be set to AAA, AAAA, vB+1 or bV+1, “Investment Grade”, “Exceptional” or “Vivid Exceptional”.
02 GIA classifies tanzanite as “Type I” and Type I is visually invisible. VVS: Visually flawless or nearly flawless, with no defects on the surface, no visible inclusions are extremely difficult to see, and there are few inclusions or defects under the 10x magnifying glass. VS: It is hard to find flawless with the naked eye. A small amount of inclusions or defects can be seen under the magnifying glass of 10 times, which has no effect on the transparency and appearance of the gem. SI: A small amount of flaws are visible to the naked eye, which has little effect on the appearance of the gemstone. I1-I2: It is easy to see more inclusions in the naked eye, which has a significant effect on the appearance and transparency of the gold couples jewelry. https://www.getnamenecklace.com/ I3: It is easy to see many inclusions in the naked eye, which has a serious impact on the appearance and durability of the gemstone.
03 The cut evaluation in the GIA colored gem quality classification system is similar to the diamond cut grade, and is comprehensively evaluated according to the polishing quality, symmetry, ideal cut ratio (depending on the shape of the gemstone), and contour of the gemstone. Emphasize the influence of the leakage window on the surface of the gemstone. The larger the leakage window of the gemstone, the worse the brightness, and the flaws are easier to find. GIA divides the gem cut into 10 levels (1~10) through the proportion of the countertop window, and divides it into excellent, good, general and poor according to the pavilion depth ratio, waist thickness ratio and crown depth ratio of the gemstone class.
04 In general, the larger the number of carats, the rarer the gem. However, since color and clarity are the main defining features of tanzanite, it will cost more for some small and pure carat tanzanite. Due to the beauty and preciousness of tanzanite, and only one place of origin, the Tanzanian government revised the relevant legal provisions of the three mining industries in July last year and established a gold and gemstone reserve mechanism under the control of the central bank. In addition, Tanzanian President John Magufuli also announced a new government order, ordering Tanzanian troops to build walls around the country’s tanzanite mining area to curb illegal mining, tax evasion and smuggling. At the same time, John Magufuli instructed the Central Bank of Bank of Tanzania to participate in the Tanzanite trade and proceed to purchase gems to increase reserves. It is reported that the Tanzanian Parliamentary Investigation Team has announced that large-scale tanzanite smuggling activities have been discovered, while Tanzania has only received 5% of the global tanzanite trade income. In response to this situation, the Tanzanian government plans to build walls in all tanzanite mines in the north of the country, install surveillance cameras and establish checkpoints. “All ore can only be accessed through an inspection gate, and even if someone swallows tanzanite ore, they will be detected at the checkpoint in the mine,” said John Magufuli.
Finally, let’s appreciate the delicate process of Tiffany Tanzanite brooch. Tiffany’s jewelers used a microscope to take a close look at the tanzanite. The jeweler casts the precious metal into a bow shape by careful polishing. This tanzanite will be placed in the center of the bow brooch. The design sketch must be drawn for each piece of the work, and the design masters Jean Sloan Berger are currently in the collection of the Art Deco Museum in Paris. The jeweler carefully checks the exact dimensions of the bow against the design sketch and does not allow for a one-minute error. The jeweler checks the joints of each metal part. Tanzanite is emerald-cut and weighs 40 carats, set on a platinum base. The colored gems that are often used in Tiffany’s jewellery, have played an important role which let Tiffany becoming the world’s top jewellery brand, with a round gold diamond earrings for women on the top 18K yellow gold bow.
