Not all diamonds are white. Impurities lend diamonds a shade of blue, red, orange, yellow, green and even black. Vivid blue, green and pink mined diamonds are the rarest. They are not the rarest gemstones, however. That title goes to a pure red ruby. Diamonds actually are found in abundance; thousands are mined every year. 80% of them are not suitable for jewelery – they are used in industry or in cheap rings.
From deep in the foothills of Mount Kilimanjaro in Tanzania comes tanzanite, one of the most intriguing and desirable precious gemstones of modern times. Exceptionally brilliant, tanzanite is unique among gemstones for its multi-dimensional color, radiating a dazzling kaleidoscope of royal blue, violet, indigo, lilac and periwinkle. 1000 times rarer than diamonds, tanzanite has enchanted discerning jewelry buyers seeking rarity and distinction. It is also a gemstone with a unique heritage, with multi-layered depths, with meaning, capturing the imaginations of today's consumers as they focus more and more on the history of gemstones, their symbolism, and their inner life of soul.
Tanzanite is found in only one place in the entire world, Tanzania, in the foothills of Mt. Kilimanjaro. The area in which it is found covers only 4 square kilometers. Considering that Tanzanite can only be found in a 4 kilometer square area and that the top quality colours and sizes are becoming harder and harder to extract from the ground it is already very rare and becoming rarer. Tanzanite is in fact considered to be a thousand times rarer than Diamonds and it's formation is so rare that it has been described as being ‘more astounding than the stone itself’. Intense geological research has shown Tanzanite's geology to be totally unique and the chance of it occurring outside the current production area is less than a million to one. Tanzanite was discovered in the mid 1960's in the Merelani Hills of East Africa by Massai tribesmen after a bush fire had heated the rough Tanzanite changing it to the stunning intense violitish, blue colour that we know.
Traditionally, the very finest Tanzanite originally came from the famed D Block Mines. This is not to say that top grade gemstones don’t come from Blocks A, B and C. Block D simply refers to the area from which material is mined. The Tanzanite mining area has been divided into 4 blocks by the Tanzanian government - Blocks A to D. Traditionally, larger quantities of the best material have been found in block D and today, when the finest 1% is extremely hard to find, Block D still produces some albeit in much smaller quantities and sizes than in the past. Some Tanzanite sellers/dealers will claim "D" block gemstones as a ruse to enhance the gemstone's value.
It is estimated that globally the wholesale market for polished tanzanite is US$200 - 300 million per annum. In general, blue gemstones are the World's most highly favored because blue is a colour that most can wear and relate to. With tanzanite, this is all the more true because of the stones extraordinary colour - at its best, a rich velvety blue with a hint of violet, reminiscent of rare Kashmir sapphires. Another reason that tanzanite gemstones are so prized is that it is available in large sizes.
Tanzanite is the most exciting gemological find of the 20th century and has enjoyed immense popularity, especially in the States, where approximately 75% of tanzanite is sold. Because of its popularity Tanzanite was added to the December birthstone list in 2004. During 1997 and 1999, faceted tanzanite was second only to sapphire in US sales of colored gemstones. Tanzanite has captured the world’s attention and is indisputably one of the most popular precious gemstones sold today along with diamonds, rubies, sapphires, & emeralds.
