Tanzanite And Diamond Ring?
Q.Watching a jewelry tv channel, the message from the presenter was " Tanz is rare, buy now while you have the chance as mines are likely to be exhausted in 9 to 10 years". Whilst I would agree that it's both an attractive and expensive gem, if the gem becomes extinct and is no longer marketed or advertised, won't the price drop - as it fades from peoples memories? Investment piece or mueum piece? Does anyone know of any other gem quality minerals, that have disapeared and what was the affect on the value. TIA.
A.Tanzanite is somewhat unusual in this regard, since to date, it's been found in only one very small geographic area. Note quite only one mine, but certainly only one geologic formation, and a rather unusual and limited one at that. There are very few gems that are found in only such limited localities, so who knows whether or not more will be found. But with that said, it should be pointed out that Tanzanite has been mined in that area for quite some decades now, and the mines, though not often producing the finest qualities that have come out at some points in the past, are still producing nice stones. Between what has not yet been mined, and what has already been mined, that's a rather large volume of the stones that now exist or will exist. Just because a stone is mined, cut and sold, does not permenantly remove it from the world. They come back into the market as used jewelry, old stock that didn't sell, and the like for some time, and if the price were to rise due to rarity, that would no doubt induce some of them to come out of hiding again. You can see much the same situation with Demantoid garnet. For many years, the only ones that made it to the market, and there weren't many, came from antiques, and commanded very healthy prices and demand. Since the Soviet Union's breakup, more have now made it to the west, many from old stock that remained in Russia, and perhaps some from reworking the old Ural mountain locations. So supply has improved. Prices have not dropped much though, in response. Similarly, Tanzanite has enjoyed enough popularity for enough decades as to have pretty much entered the realm of fairly well recognized gems. I doubt that it's mine finally running dry, if that indeed happens at all, will cause it to quickly disappear into obscurity. I wouldn't be at all suprised if a new deposit it found (coincidently) as the old one dries up. I think the industry has spent too much in promoting this one. Although it is a fav of my wife, only small clusters affordable these days. If she wants 1.5 cts+, she'll have to setle for Iolite.
