In 2018, the first year of Chinese diamond cultivation, the three-year boom accounted for almost half of the world's total production. As a consumer, it is a new thing. What is it really like to grow a diamond?
With every new thing comes a bumper harvest of leeks.
If we grow diamonds, let's be honest, we all become "roughnecks", don't step on the hole?
First truth: Are synthetic diamonds indistinguishable from natural diamonds?
Cultured diamonds are also diamonds. Its elements, hardness, and refractive index are the same as natural diamonds. You can't tell with the naked eye, only with professional instruments.
Second truth: What are the pros and cons of CVD and HPHT for diamond farming?
Advantages of CVD: can be used to drill large carats, 3-5 carats is not uncommon.
Disadvantages: GH color is average, and EF color will be upgraded by changing colors (
Try to avoid discoloration of drilling holes.
Advantages of HPHT: high color level, generally achieve DE color, late without color change.
Cons: Most are under 2 carats, and few are above 3 carats.
Fact # 3: Are the certificates and standards for growing diamonds reliable?
The International Certificate IGI GIA is a certificate for the cultivation of diamonds, and the reference standards are exactly the same as those for natural diamonds. The cover has the text: Cultivate Diamond, which will have 4C, Color Clarity Cut, Whether to Change Color and Cultivation Method (CVD HPHT). Therefore, the cultivation of diamonds with an international certificate is unquestionable and reliable!
Domestic certificate NGTC NGIC, NGTC detection standard is very high, so there is no need to worry. But merchants rarely issue such certificates because the process is too complicated. NGIC is relatively loose, there are operational risks of skipping classes. For example, the actual diamond clarity is SI1, then the certificate is VS2, cut VG to EX. There's no standard way to grow it (that's okay), and there's no standard way to change the color (you'll have to ask the vendor).
This kind of certificate is not to drill, may not be! Because the certificate is cost-effective, generally cheaper than the international certificate of hundreds of thousands, but must be selected, and cut, to see whether there are defects with the naked eye. Even VG can pick out a good drill. EX Cut does not mean perfect!
The fourth truth: How to choose a diamond to get the best value for money?
Generally, when cultivated diamonds reach more than 1 carat, the price starts to rise. If you don't have to go for carats, choose a few points depending on your budget. For example, a 50-cent bred diamond DE Color +18K gold ring holder costs around $4,000, and you don't have to save a fraction of the price for a standard natural diamond of at least 1.7-1.8W.
If you want a larger 90, FG color +18K finished ring, then 8K+ should be able to win, the standard diamond of the same level needs 3-4W.
If large carats are needed, the bigger the diamond, the more expensive it will be and the biggest the profit margin for the business.
So you can bargain as much as you can so that a thousand dollars are possible.
