You now know that the big 12,000 carat rough tanzanite rough that was found was in a rough form. So how just how big would the same tanzanite be after being cut, faceted and polished. What we need to understand is that rough tanzanite will have inclusions, fissures (cracks) and even color zoning across the piece. You therefore cannot get one big tanzanite piece after cutting and polishing the large rough tanzanite piece. During the cutting and faceting process, expert cutters will break the large tanzanite rough into smaller pieces. Care will be taken to ensure that each of those smaller pieces do not have too many and too visible, fissures or inclusions. Basically the inclusions and also the areas with too many fissures will need to be cut away. Another task that remains is the try to ensure as uniform a color as possible across each of these smaller tanzanite pieces. So the big tanzanite rough that weighs 12,000 carats will probably be broken into smaller pieces - you might end up with as many as 1,000 to 2,000 smaller pieces of tanzanite. There is no point in trying to get 1 large 10 carat tanzanite cut and polished gem if the piece is going to have visible cracks and inclusions. Similarly, no gem buyer would be interested in a 10 carat tanzanite gem that has color patches (zoning) across the piece. So there is no fixed number of smaller tanzanite pieces that will be cut, the condition of the large tanzanite rough will decide that. From experience we could say that the gem manufacturer would get, at least a few pieces of good quality tanzanite cut and polished gems that weigh 8 to 10 carats each. At the same time there could most likely be around 200 pieces that weigh less than a carat each. By general standards a good quality tanzanite that, weighs around 5 carat or more can be classified as a big tanzanite gem. The manufacturer would price all the stones cut from the big tanzanite rough gem. Color, clarity, size and the presence of inclusions and fissures will all influence the price set for each of the smaller stones. In gemological terms we refer to this as the 'yield' received from cutting rough gems. The above explanation should answer most of your questions. The main thing is that there is no question of a 12,000 carat cut and polished tanzanite gem. The original piece was a rough tanzanite stone. The smaller pieces cut from this large rough tanzanite would weigh just about 10 to 12 carat at the maximum. Most of the pieces after cutting and polishing would be in the 1 carat to 2 carat size range. Kaisilver can custom make all types of tanzanite jewelry, in 14k or 18k gold. We can infact custom make silver tanzanite jewelry too. The designs for your tanzanite rings and other tanzanite gem stone jewelry can be yours or ours. We procure all tanzanite gems from the Tanzanian mines and custom cut the gems ourselves. This will not only reduce multiple commissions through multiple middlemen but, also ensure that you get a natural tanzanite gemstone and not a factory made substitute.
