Real diamonds grown in the laboratory constantly offer a tempting prospect to make the beauty 鑽石 of real and real diamonds accessible to jewelry lovers all over the world. Unfortunately, there is still a wide gap between typical press articles and the reality that diamond laboratories can develop as of November 2009.
Thus, this article aims to train diamond buyers interested in buying a real lab-grown diamond to make sure your expectations are realistic and understand what is available and what is not (and why). In addition, this article can help avoid falling into the trap of unethical sellers of C.E.C., who advertise their product as a ‘laboratory diamond’ or ‘artificial diamond’, although in fact the C.E.P.A. is the subject of misleading advertising.
Since the publication of our last paper in 2007, minimal progress has been made with larger white diamonds grown in the laboratory, but not for lack of effort on the part of scientists. Buying a lab-grown white diamond 2 carats of true jewelry quality with the same probability as a unicorn right now … reality existed in November 2009, not now.
Only two laboratories have publicly stated that they are currently working on growing white laboratory diamonds for the consumer market. Although the lab had several sizes such as 1ct, it has been rare and difficult to reproduce until now. Even after years of research and effort, a typical diamond produced weighs less than 50 carats, and often its color is lower than that of a conventional diamond of jewelry quality. The few that are available are usually sold for the same price or more expensive than a comparable white diamond extracted from natural sources, and the waiting time for larger sizes (0.75 carats and above) can be more than a year without a guarantee if and when you can do so. . Buy. Thus, the reality is that no diamond dealer can offer laboratory white diamonds on a permanent basis, easily accessible and more than 1 carat in size (as of November 2009).
Because of this discrepancy between supply and demand for real lab-grown white diamonds, there are still some sellers of C.E.O. advertising, perhaps even next to this article, where they say, ‘Flawless artificial diamonds’, ‘Perfect diamonds created in the lab’. Or similar. false claims. These are unethical sellers who sell a regular C.I. and change their advertising tactics. Their product is not a real laboratory diamond (carbon), but rather, the C .S.C., a widely available artificial diamond material that mimics the look of a white diamond, but it’s not a real diamond. Plain C’s has been available since the 1980s and is nothing new to the jewelry market. The only problem is the number of sellers who have benefited from the gap in consumer knowledge between articles in the press overly stating the availability of real lab-grown diamonds and the limitations of what is really available in real white diamonds.
It is hoped that white diamonds larger than 1 carat and larger will eventually blossom, but so far the market is still limited due to the extreme difficulty of growing white diamonds desired for consumers sizes.
Blue diamonds grown in the laboratory are the only strong point in today’s market for lab-grown diamonds. Blue diamonds extracted from natural sources are created when grown in the presence of boron, so they have a rare and unique blue color. Blue diamonds of saturated saturated blue color (Fancy Vivid Blue is the term “diamond”) of any reasonable size are extremely rare and, when available, are almost always sold at auctions (Sotheby’s or Christies), so the seller gets the maximum value for what is likely to be a one-off sale. As a result, natural bright blue diamonds can have a price from $565,000 per carat to $1.3 million per carat. The bright blue diamond at auction is a media event, and the press regularly calls it one because of its exceptional rarity, beauty and dazzling prices for mined blue diamonds.
Prices for lab-grown blue diamonds range from $5,000 to $10,000 per carat ($2,500 – an average price for a 50-carat stone). Not cheap, but an incredible deal compared to the price of its mined counterpart. The price item here should show the contrast between the real lab-grown diamond and the C.E.O., sold as a ‘laboratory-grown diamond’ at a cost of $150 per carat. $150 per carat would not even match the cost of the cut material, so simply by setting the price, you can easily determine which sellers are selling real lab diamonds or engaged in bullying and advertising.
In terms of the beauty of diamonds, while the chemical composition of the grown and extracted in the laboratory of blue diamonds is the same (carbon plus boron), the blue diamonds grown in the laboratory easily exceed their naturally produced. The reason is the cutting standards used. The cut controls 98% of the diamond’s brilliance and therefore the beauty of the diamonds. Most natural blue diamonds are poorly cut to retain as rich blue as possible, and because of the simple fact that cutting to achieve optimal beauty (lightness in circulation) will result in a much smaller weight in carats of finished products.
When you are dealing with incredibly rare and expensive material (again, up to $1.3 million per carat and is considered one of the most valuable materials in the world), the focus is on maintaining the possible weight of the finished product. Thus, the cut of maximum beauty gives way to a cut of maximum size. In terms of pure diamond cutting, some natural blue diamonds are probably among the worst-cut diamonds available, with large windows that allow light to pass through them, rather than reflecting because of the emphasis on maximum final size (steep corners provide better light processing, but also mean a smaller size of finished products).
On the contrary, the lower cost of laboratory blue diamonds means that they can be limited with an emphasis on the beauty of the diamond, not just the cut. For example, the recently sold lab blue diamond was the size. Grown in the laboratory Fancy Vivid Blue Diamond 63 carats, which was independently rated as the perfect round diamond …
