1. What’s the difference between Natural and Lab Grown Diamonds?
Natural diamonds are mined from the earth and are commonly known as earth-mined diamonds. In contrast, lab-grown diamonds are created in a laboratory. As such, the chemical composition is virtually identical to natural diamond.
GIA has written an excellent article on the subject:
There are currently two methods for producing lab-grown diamonds:
- a) HPHT is an abbreviation for “High-Pressure High Temperature.” We do not use HPHT material to produce Brian Gavin Signature Lab-grown diamonds because sedimentary-like layers of brown undertones are a side-effect of the process.
- b) CVD is an abbreviation for “Carbon Vapor Deposition.” Brian Gavin uses select CVD material that is grown in Texas. After years of research, we partnered with an amazing Company “Clarity” that has a unique patented growing process.
Unlike most companies, Clarity is able to grow the crystals in one shot irrespective of size. In contrast, other growers must interrupt the process and create the crystals with multiple layers.
In addition, the lab-grown crystals by Clarity are warranteed to not undergo any post-growth treatments, whereas most lab-created CVD diamonds do require treatment to improve color. During the grading process, if GIA cannot determine that there has been no post-growth treatment, their default is to note that the diamond has evidence of post-growth treatments.
The advantage of using the higher grade material by Clarity is that it has greater transparency. Coupled with the Brian Gavin patented process for exacting light performance (patent #link) we’re able to provide you with the most brilliant and sparkly Lab-grown Hearts and Arrows diamonds on a global scale.
