• Lab-grown CVD Diamonds.

CVD stands for Chemical Vapour Deposition, and is the commonly used name for diamonds grown in a laboratory via a process of chemical vapour deposition. These lab grown stones are identical to natural diamonds. CVD diamonds have the exact same properties as natural diamonds, possessing the same internal structure, chemical makeup and physical, lustrous beauty. Just like natural diamonds, CVD diamond properties include great durability, reaching 10 of the Mohs scale of hardness, and intense brilliance. 

Lab diamonds are becoming an increasingly popular choice amongst engagement ring and jewellery buyers - and along with HPHT, CVD is one of the most commonly used production methods. Some of the benefits of CVD diamond jewellery include ethical origins, sustainability, and cheaper prices.

CVD diamonds are rare to find totally flawless - some will be heavily included and poorly coloured, while others will be totally colourless, with only minuscule imperfections; just like natural diamonds. Look between SI1 and VS1 clarity grades, and D to F colour grades, for a diamond that appears top quality and provides value for money.

CVD Diamond growth process:

•Chemical Vapour Deposition (CVD) diamond making process.

• a very thin diamond seed is selected and placed in a sealed chamber.

•The chamber is heated to around 800°C and flooded with carbon rich gas.

•The gas ionises, breaking down into pure carbon.

•The pure carbon molecules attach to the original diamond seed.

•This process continues until a fully formed diamond is created.

•CVD diamond creation requires a highly-specialised, scientific process that has been perfected over many decades, to produce jewellery-quality diamonds in an efficient and relatively speedy way. Chemical vapour deposition is a scientific process used to create a number of solid materials, often for use in the semiconductor industry - that has been adapted to create diamonds in two to four weeks.

•A thin slice of diamond, around 300 microns thick and 10x10mm, known as a ‘diamond seed’, is selected and thoroughly cleaned. The diamond seed must be clean, as any trace elements or imperfections will be crystallised during CVD diamond growth, creating inclusions and blemishes. This diamond slice is typically taken from a high quality diamond created by HPHT.

•The diamond seed is placed into a sealed chamber which is heated to around 800°C. The chamber is flooded with carbon rich gas. The chamber must be completely sealed, to avoid any other gases from entering and disrupting the diamond’s growth.

•The carbon rich gas ionises under the intense heat, meaning its molecular bonds break down and settle on the existing diamond seed. The pure carbon molecules bond to the diamond seed, building and building as more gas ionises and bonds to the existing diamond. This crystallisation continues until a fully formed, rough diamond is produced, and the process is ended.

•CVD diamonds are grown very quickly, which can cause less beautiful traits, like graining, spotty inclusions and brown tints. These can be removed or improved with a post-growth HPHT treatment. This improves the overall look of the diamond, but may causes milkiness.
