Rhinestones and physicochemical properties and value of natural diamonds different?

No specific figures verified, but this text say things most is right.

Currently diamond for industrial use mainly synthetic, because of low prices. The current annual production of synthetic diamonds is several billion carats, while production of natural diamonds only over 100 million karats. However, the vast majority of synthetic diamonds are small particles of diamond, color is also poor, can not be used for jewelry purposes, so the vast majority in the vast majority of synthetic diamonds are used for industrial purposes, natural diamonds inside, there are half use for industrial use, the proportion of diamond jewelry used in diamond output is very low which accounted for.

The cost of synthetic diamond jewelry class is entirely another matter. Jewelry grade diamonds require large particles, but also purity, color, impurities, and so there are stringent requirements, the cost will increase many times. It figures a few years ago, the natural production of colorless or near colorless diamond jewelry grade diamonds, the average cost is about $ 40-60 per carat, while the same grade synthetic diamonds, the cost is about $ 2,500 per carat. But diamond synthesis technology advances rapidly, and now the price can be cheaper possible. Moreover, since the diamond pricing is very special, the higher the price the greater the head, carat diamond sales price is substantially more than a few thousand dollars, so even if the cost of a few years ago, on several carats this weight class, synthetic Diamond has a profit. Synthetic diamond jewelry level has also entered the market, diamond jewelry, about 2% of synthetic diamonds. One can see what practice is to use (hair mostly) on the enemy's body as a raw material to synthetic diamonds as a souvenir, this selling valuable than natural diamonds. Ordinary diamond jewelry sales channels inside, because the current natural diamond manufacturers in the exclusion, synthetic diamonds could not leave with grade identification of large organizations, so the price is good, the market should be invisible.
Different methods of synthesizing diamonds, there are some crystalline characteristics, as impurities caused by production method itself is also a feature of the use of modern equipment is easily discernible, but the use of traditional jewelry diamond 4C method can not be identified. Currently large diamond companies have a simple device can distinguish synthetic diamonds and natural diamonds, the use of commonly used laboratory infrared, ultraviolet, X-ray and so on enough points clear. De Beers is designed to distinguish synthetic diamonds even simple testing equipment, the use of the ultraviolet spectrum.

As the price of diamonds worth the money, which send the diamond to see what the result is later. Hundreds of thousands of dollars lie a large living hand if successful, it is still very cost-effective. For carat diamond below the rank of sales price is relatively low, the current cost of synthetic diamond jewelry level also too high, do not cost a small, should not touch synthetic diamonds (of course being cheated zircon that would not work, zirconium the difference between stone and diamonds are experienced eye can distinguish, after all, different refractive index). Carat or more, at least on the market today are synthetic diamonds go special sales channels, the actual selling price is also more expensive than natural, the possibility of buying a diamond can meet ordinary synthetic diamonds is extremely low. But there are many other fake diamonds methods by other processing means is diamond grade changes is possible to do so, these methods have traces can be detected, but depends agency approach certificate is not serious. So buy a diamond certificate of election have a good reputation is very important. However, if the price has obvious advantages, the seller is also honest diamonds are treated, then some people will accept such a diamond, after all, this so-called fraud, get the jewelry, in fact, can not tell a difference. Such diamonds tend to occur on the following five very small drill.
As synthetic diamond jewelry whether it will impact the natural diamond industry, I feel is unlikely. Big head grade synthetic diamond jewelry from a cost point of view actually still difficult to compete with natural mined. Currently too many links natural diamond industry, the layers increases, and only then the final sales price of diamonds fried very high, the actual mining costs and not so high, or natural diamond industry is actually a small price decline in space is not needed if the cost is no advantage out of synthetic diamond jewelry market without any problems. Synthetic diamonds to natural diamonds really a threat, costs also need to drop by at least an order of magnitude. The difficulty of growing large crystals of the high cost of it is high, it is difficult to say reduce the cost of this magnitude is truly viable. Grade synthetic diamond jewelry unless costs can be much lower than the natural mining, large-scale synthesis Jewellery Diamonds otherwise inevitably lead to the collapse of diamond prices, the first to die of their own, this is a market totally suicidal behavior, the possibility is not high.
And luxury goods industry is a very interesting market, a large supply of high quality and low prices of synthetic substitutes for breeding may not be able to suppress the price of natural products. For example, many precious stones semi-precious stones have already synthesized and the price is not high, the supply is not small, but still be able to sell high-priced natural products.

Therefore, synthetic diamond jewelry level should continue to be in a very particular market to survive, but it is difficult to influence the price of natural diamonds.
