Our integrated partners:. Punya Pertanyaan? As a result, from —6, production from the company improved to more consistent commercial volumes. It must be noted that at no point can a geologist predict the gemstone; we are always predicting the geology in which the gems are formed. From mid, the consistent production from the mine was a result of having the mining faces in the right areas.

If one face was not producing, another one was. Large-scale mining operations generate not only more production volume, but also more volumes of all grades, more consistently. As a result, a master grading set was created. For the first time, rough Tanzanite could be parceled for size, colour and quality to its sightholders. By definition, this system of product presentation for rough sales could only work with regular and good volumes of production from the mine.

This was a direct result of the size of the deposit being professionally mined, with regular production and future exploration. But the story does not end there. Because it is commercially available does not mean that Tanzanite is any less rare than it originally was.

It just became accessible to everyone; but only for a limited time: our lifetime. Found for the first time in , it can be estimated that the gemstone will no longer be accessible, particularly commercially, within a single generation of its discovery. The most common understanding of this is that the deposit gets physically exhausted mined out , but the actual concept is that the costs to mine become too high versus the income from sales i.

This factor highlights its generational rarity, which the current market and value of Tanzanite do not indicate. The market and consumers think that because there are high volumes of Tanzanite available at the moment this will continue; but this not the case. The current prices of Tanzanite, particularly at the wholesale level, are actually too low; too low for how rare the gemstone is, and too low for future mining. The amount of Tanzanite on the market currently should be seen as a bubble and temporary; it will not continue.

There has been a lot of recent supply due to many miners being in the right areas and producing, with this product subsequently making it to the wholesale market. This is the reason for the low wholesale prices, but with the mines getting deeper, and the natural pocket effect of Tanzanite, this will not continue. The reality is that the deeper the mines get, the more expensive it will be to mine.

For future years of supply, the wholesale prices need to increase. Single generation is a phase coupled with Tanzanite since its marketing in the s, and this itself, evokes its own romance, beauty and rarity.

Trying to tie the availability to a number of years should not be the discussion point, and according to me, less importance and significance should be given to it. The history of the talk of only available for another 10 years, or 15 years ties in to large-scale public mining at companies attempting to quantify its resource for value purposes and investment, which the previous owners in the s took to the market to create desire and indicate its rarity.

There are too many factors that affect a number like this, so it should only be seen as guide and less importance should be given to it. There are a lot of options for stones like diamond, which is valued for its hardness and thermal conductivity, making it useful for making cutting and grinding tools such as drilling bits. It can also be powdered for polishing other gemstones. Every diamond that enters the world market is controlled by organisations such as DeBeers, but tanzanite has no such system.

That means the entire tanzanite industry is operated by supply and demand. The Tanzanian Government has tried to produce certificates of origin for tanzanite, which would mean the importers or exporters would be obliged to go through legal channels.

However, the main importers like India and the USA do not yet recognise them as official documents, meaning smugglers have no problems when selling tanzanite.

Smugglers who sneak out stones from the mines for illegal trading do not operate openly or pay taxes to the government from their sales. This means mining companies have a hard time keeping up. In fact, international gemstone mining company Richland Resources used to own half of Tanzanite One, the company with the largest mine in the area.
