Market for imperfect gemstones?
In another newsgroup someone made the claim that the existance of
synthetic gemstones had not affected the market for natural ones. I would have thought that the market for less-than-perfect gemstones, at the typical-American-consumer level would have disappeared once perfect synthetics started competing with them. I am not of course counting lapidarists, rockhounds, etc. who appreciate natural stones for themselves. But taking myself as an example, an imperfect emerald in its original columnar crystaline form and still attached to a bit of matrix rock is a thing of beauty and worth collecting; facet it into a traditional "emerald" shape, and I would find nothing to make me desire it over a flawless lab grown gem. So what is the straight scoop? Are less-than-perfect natural gemstones prefered over perfect lab grown ones at the retail level? -- Please reply to: | "Any sufficiently advanced incompetence is pciszek at panix dot com | indistinguishable from malice."

Usually, yes. The effect of synthetics on the gem market has been interesting over the hundred years or so that various synthetics have come on the market. By making a great looking yet inexpensive version of a gem available at all, the public's awareness and appreciation of colored gems has increased. *Overall demand for gems, both natural and synthetic has been increased by the synthetic's availability. And an interesting effect: *Because many of the cheapest synthetics are virtually flawless, similarly flawless natural stones end up being confused with synthetics. *The result is an increase in the demand for some of the less perfect natural stones, since their pedegree as natural is much more evident. In some cases, such as amethyst, *where the synthetic is not only almost always flawless, but is also quite difficult to identify as such even by jewelers, what's happened is that the price of the finest natural qualities, with which the synthetics compete, has actually fallen some, while the natural stones with a few inclusions, has risen. In general, early fears that synthetics would replace naturals has not proven to be the case. *The demand is not just for the look or durability, etc, of good gemstones, but also considerably for the rarity of fine natural stones. * It's that rarity, exclusivity, natural origin, mystique, *and maybe even just plain snob appear, even when the naturals are not really all that rare (like diamond) that drives this. * Synthetics support the lower end of the market so people who like the look fine gems but cannot afford the natural ones, still get much of the enjoyment. *Meanwhile, those same synthetics increase the appeal, demand for, and price, of the rare finest gems. * Peter Rowe G.G. That's pretty interesting stuff.... Makes sense too. I have a question concerning RAW diamond or Utility diamond as some refer to it. It's typically brownish in color. Do you know the type of which I am refferring to ? I would like to obtain some of that stone and don't know where to get it. I wouldn't mind finding a respectable supplier of those 'slightly' included stones of which you both mentioned as well.... Cheers, /FC.... |

I would like to obtain some of that stone and don't know where to get it. Usually called industrial diamond or just uncut diamond crystals. RAW simply means uncut, which could be gem grade or not. That word is not a common used one, at least not that I've seen. Uncut, natural crystals, etc. yes. Utility? never heard that word applied to diamonds at all, but maybe I've been living in a cave or something.. As to a source, for true industrial stuff, normally used for cutting tools, I can't help you, at least not in usably larger sizes. Abrasive grit is easily enough found through lapidary dealers. But for better looking/attractive natural diamond crystals, you can find a number of sellers on ebay, and usually the gem shows that commonly travel around the country often have at least a few dealers who'll happen to have a few decent looking diamond cube crystals as specimin pieces. A couple of the ebay sellers often have nice natural crystals that are actually bordering on gem grade, or even gem grade. I've seen some quite white and mostly clear looking octahedral crystals offered. Some might even be cutable. More expensive than the typically non-transparent little cubic crystals you also see offered. A number of well known art jewelers enjoy using these stone in preference to the typical cut gems. Totally different look, yet still diamond. By the way, colors, while often in the yellow to brown range, can be a wider range. Milky white to grey, for example, is also common. I wouldn't mind finding a respectable supplier of those 'slightly' included stones of which you both mentioned as well.... Any decent gem dealer will have such. Most natural gemstones fall into that catagory with at least some inclusions. Those few gem types that are commonly available in a pretty clean state, are still available with more inclusions, usually pretty cheaply. Again, such stones are not hard to find. They make up the bulk of the gemstone trade. That includes diamonds, as well, by the way. Any decent diamond dealer will have a good supply, maybe a majority with some dealers, of the at least slightly visibly (sometimes with a bit of magnification) included stones, than really clean ones. Flawless natural diamonds are quite rare, not to mention rather costly.. Peter |

Peter Yes, You are correct. My terminology was poor as a descriptor.... The diamond I am referring to is indeed the 'natural diamond' (see link provided). The amount and quality of diamonds coming out of the Kimberlite pipes in Alberta and surrounding Provinces are supposed to be world class, so you WOULD THINK that they would be EASY to find here...... Not so.... I think DeBeers likely has enough money invested in these projects that they get first crack at anything coming out of the ground. I would have assumed that RAW diamond would have been far less expensive compared to a carefully 'cut and crafted stone'. http://www.khulsey.com/jewelry/rough...d_jewelry.html Cheers, /FC.... |

Whether or not DeBeers has anything to do with it is not the point. No dealer would sell you a fine gem grade rough cheaply, if, with a bit of effort on the part of a cutter, the value could be increased many times. If he'll sell you such rough, it will be at a price proportional to it's potential as a cut stone. And finding a dealer who'll bother with a retail buyer at all, is your real problem. These folks deal in quantities, and large amounts of money. You can't walk into the main factory floor at GM, and buy a car. You have to go through the dealers who sell the finished goods.

That's one reason they can find them for sale. And indeed, the prices per carat are Much less than the prices per carat for cut stones. But you still have to go through at least some semblance of the usual distribution channels. In this case, that would be finding a gem and mineral dealer who sells such crystals. By the way, just because the Canadian mines produce lots of high quality rough doesn't mean you'd be able to find lots of these decorative lower quality goods. different mines have different characteristics in terms of the type of crystals they usually find. While I don't know whether these little cubes are not common in the Canadian mines, I do know that the one's I've bought and seen in the past have not been Canadian sourced. It's always possible that such rough just isn't as common in the Canadian mines... Peter |

Peter * You are correct about the Diamond from Canadian Mines. Almost ALL of the diamonds are basically transparent in color. Very few are even Yellow. My assumption is that it must have something to do with the Kimberlite pipes but I'll wait for a reply from the "Diavik" mine in relation to that question. It seems that the darker it gets, the less expensive they get...(sort of). I've found A LOT of black diamonds for less than $100.00 / Carat that were cut and faceted to some degree... I am however, still having a tough time finding those Diamonds that look like the one's in "Todd Reed and others works". It looks like I'm going to have to keep looking for awhile. BTW, there are a number of mines in Canada where you can in fact go 'directly to them' to buy gemstones or 'cultivate' your own. BC is a very popular place for this, along with a couple of Ammolite mines in Alberta. The prices are of course 'Higher' than that of which a wholesaler would pay, but never the less, it is possible and the grades are VERY high. On a side note, I went to a flourite mine in BC last year and extracted some 'beautiful' pieces of "Bearite" from the surrounding rocks (they blast small portions of the cliffside away exposing new rock once or twice a month during the summer..). It's quite interesting, because you can take with you, as MUCH as you can carry. The problem is the hike is quite BRUTAL and if you take to much you aren't going to make it back ! Lot's of fun though... Cheers, /FC.... |

These are the browns that come from Australia.

Hmmmm, that is rather odd. Some of the pricing structure of different vendors is waaay off the map, it seems. I found a few of the 'raw diamonds' that I was looking for (locally) and they wanted an arm and part of a leg for them..... I don't believe I'll be using them for a project in the very near future due to their present cost. I think maybe I'll head on over the the Lapidary shop and pick up some different types of rock and stones to experiment with instead. It's mind boggling how many stones, metals and rocks are available in those places now.... Cheers, /FC.... |
