Lab-grown diamonds that are identical to natural diamonds. They are sometimes referred to as CVD diamonds or HPHT diamonds. They are comparable to natural diamonds in terms of their chemical, physical, and visual characteristics. These diamonds have grown in popularity over the past ten years, and are precisely like a natural diamond.
Chemical Vapor Deposition, or CVD, is one of the two procedures used to make diamonds in a laboratory. Natural gas, such as methane, is broken down by CVD techniques into carbon atoms, which combine to generate new diamonds. High-Pressure High Temperature, or HPHT, is the alternative technique.
What Is A CVD diamond?
The term "chemical vapor deposition," or CVD, is frequently used to refer to the procedure used to create diamonds in a laboratory. This is distinct from HPHT. Another method frequently produces lab diamonds (High Pressure High Temperature).
CVD diamonds are genuine and comparable to natural diamonds. With specialized tools, it is possible to distinguish a CVD diamond from a natural diamond.
Properties Of Lab Grown Diamond
-
They share the same physical, chemical, and visual characteristics as natural diamonds.
-
They have remarkable durability and a Mohs scale hardness rating of 10.
-
They can have imperfections, just like natural diamonds, and it is uncommon to find one without inclusions.
-
Using the 4Cs properties—color, clarity, cut, and carat—professional labs rate them.
-
When certifying a lab grown diamond, reputable labs include the diamond's origin.
Lab Grading And Certification
Lab grown diamond diamonds are rated like natural diamonds for their carat weight, cut, color, clarity, fluorescence, polish, and symmetry, among other characteristics. Other grading laboratories certify lab-created diamonds worldwide, but GIA and IGI are the most reputable.
Both GIA and IGI evaluate lab grown diamonds for their properties to provide an accurate assessment of their quality. This information subsequently influences the stone's pricing. The girdle of the stone has a unique code that GIA and IGI laser stamp; this code, which can only be seen under magnification, corresponds to the paper (or digital) certificate, which contains all the information about the stone, including its grades, carat weight, and measurements.
How Are Lab Grown Diamonds Made?
- The experts choose a thin diamond seed and place it in an enclosed chamber. * They fill the chamber with carbon-rich gas while heating it to roughly 800°C. * Pure carbon is created when the carbon-rich gas ionizes.
- The pure carbon atoms adhere to the first diamond seed.
- The lab carries out the technique until a natural diamond is produced. * Depending on the details of the diamond, the process could take 5–10 days or even 6–8 weeks.
The Pros And Cons Of Lab Grown Diamonds
Pros
- More affordable than natural diamonds.
- Because they are made in a lab, they are environmentally friendly. * They come in a variety of sizes, colors, and forms.
- They can be developed in 6-8 weeks, less time than large-scale mining for genuine diamonds, and they have fire, sparkle, and brilliance.
Cons
- They don’t come from the earth.
- Are tricky to find in popular shapes & sizes.
- Not sold by many brands.
