Can I buy lab grown diamonds from the UK

Yes, you can buy lab-grown diamonds in the UK. There are several reputable retailers and online stores that offer lab-grown diamonds, including companies like Pure Carats, Lark & Berry, and Diamond Foundry.

It’s important to note that lab-grown diamonds have become increasingly popular in recent years as a more sustainable and ethical alternative to mined diamonds. Lab-grown diamonds are created in a laboratory setting using advanced technology that replicates the natural process of diamond formation, resulting in diamonds that are physically, chemically, and optically identical to mined diamonds. They are also generally more affordable than mined diamonds of the same quality and size.

Before making a purchase, be sure to research the company and their policies regarding lab-grown diamonds to ensure that you are getting a quality product and that the company is reputable.

It’s worth noting that while lab-grown diamonds are chemically and physically identical to natural diamonds, they are not the same as diamond simulants like cubic zirconia or moissanite, which are entirely different materials. Lab-grown diamonds are made of pure carbon and have the same hardness, brilliance, and fire as mined diamonds.

Also, when buying a lab-grown diamond, you should make sure it comes with a grading report from a

reputable gemological laboratory such as the International Gemological Institute (IGI) or Gemological Institute of America (GIA). This report will provide you with important information about the diamond’s quality, including its carat weight, colour, clarity, and cut.

Another thing to consider when buying a lab-grown diamond is the type of production method used. There are two main methods for producing lab-grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods produce high-quality diamonds, but they differ in terms of their production process and cost.

HPHT diamonds are produced by mimicking the high pressure and high temperature conditions that occur deep within the Earth’s mantle. This involves placing a small diamond seed crystal into a press and subjecting it to high pressure and high temperature conditions to encourage diamond growth. HPHT diamonds tend to have a more yellow or brownish colour, which can be treated with additional processing to improve the colour.

CVD diamonds, on the other hand, are grown in a vacuum chamber using a gas mixture of carbon-rich gases. The gases are ionised, causing carbon atoms to rain down on a diamond seed crystal and build up layer by layer. CVD diamonds tend to have a higher clarity and a more colourless appearance than HPHT diamonds, making them more desirable for certain applications.

Finally, it’s important to note that lab-grown diamonds are still relatively new to the market, and some people may still prefer mined diamonds for personal or cultural reasons. Ultimately, the choice between a lab-grown or mined diamond is a personal one that depends on your values, budget, and preferences.
