What’s Synthetic diamond?

A synthetic diamond (also known as a laboratory-grown diamond, a cultured diamond, or a cultivated diamond) is a diamond produced by a controlled process, as contrasted with a natural diamond created by geological processes or an imitation diamond made of non-diamond material that appears similar to a diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). While the term synthetic may sometimes be associated by consumers with imitation products, synthetic diamonds are made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form.

What Are CVD Diamonds?
A CVD or Chemical Vapor Deposition Diamond, also referred as a laboratory-created Diamond, is produced by means of a synthetic method, as compared to real or Natural Diamonds, which are generated by physical processes. In addition, CVD Diamonds started appearing in the gemstone Diamond market many years ago. This process involved bringing a gas like methane into a vacuum chamber and then activating and breaking down the molecules of the gas with microwaves, which causes the carbon atoms to accumulate on a substrate like the way snowflakes accumulate in a snowfall.

 

What are the Methods to create the CVD Diamonds?

laboratory-created Diamond-Chemical-Vapor-Deposition-Diamond-China-WholesaleThere are now mainly two methods of manufacturing CVD Diamonds, the first is the HPHT or High Pressure High Temperature process and the other is CVD or Chemical Vapor Deposition. The HPHT method was used to successfully grow Diamonds in 1956 by General Electric, and basically mimics the natural process. The HPHT process and the energy and equipment needed is costly and produces Diamonds with mostly brownish or yellowish colors. On the other hand, using the CVD process is inexpensive because it works at moderate temperatures with a low pressure that needs smaller and less costly tools. Colorless crystals can be grown as the vacuum chamber contains mainly carbon and some hydrogen. Yellow or Blue CVD Diamond crystals can be produced if boron or nitrogen is introduced into the chamber.

FAQ of Lab Diamond Stones:


1.Q:Are lab diamonds real diamonds? 

A: Although there is some confusion on whether natural diamonds are the same as lab grown diamonds, we’re here to inform you that lab diamonds are in fact real diamonds. … This remarkable lab grown diamond (also known as a synthetic diamond) has the same sparkle, clarity, and aesthetic of an earth mined diamond.
2.Q:Why are lab diamonds so expensive?
A:Synthetic diamond prices are generally lower than natural diamonds, and the price of lab-created diamonds continues to drop (as much as 30% in a year). This is due to lab-grown diamonds not having any resale value and that the demand for lab-grown diamonds continues to decrease.
3.Q:Are lab grown diamonds better?
A:Lab-grown diamonds are real and they’re fantastic. They’re also ethically-sourced, eco-friendly, and far more affordable than their mined counterparts. For proof, look no further than Clean Origin, one of the best names in the game when it comes to lab-grown diamond engagement rings.
4.Do Lab created diamonds get cloudy?
A:Lab-made diamonds typically have good clarity. Like a high-quality natural diamond, lab-made diamonds won’t get cloudy.
5.Q: Can you tell the difference between lab grown and mined diamonds?
A: There is no visible difference between the two. Even a professional gemologist will need specialized equipment to tell which is which. With magnification, a professional will be able to make out small contrasts in the inclusions of lab-grown vs. mined diamonds.
6.Q: What’s the highest quality Lab diamond?
A: FL (or Flawless) is the highest grade for clarity. An FL diamond has no imperfections even when magnified 10x by a professional. For color, D or completely colorless diamond is the highest grade. While flawless and colorless diamonds are extremely rare, cut determines a diamond’s true value.
7.Q: Are lab created diamonds worth anything?
A: Lab-created diamonds have very little to no resale value. That means if you buy a lab-created diamond, you won’t be able to reap any part of what you paid for it. For example, if you bought this 1.20ct lab-created diamond, you’d have a beautiful stone, yet no jeweler will buy it back.
