  • What is a labgrown Diamond?

    A lab grown diamond is a man-made gemstone created in a controlled laboratory setting. While it possesses many of the same characteristics as a natural diamond, it lacks the deep history and romantic allure of diamonds formed over millions of years beneath the Earth's surface

  • How are Lab Grown Diamonds Made?

    Lab grown diamonds are manufactured using technological processes like HPHT (High Pressure Heat Treatment) and CVD (Chemical Vapour Deposition). Unlike natural diamonds, which are forged by nature over millennia and carry a unique story, lab-grown diamonds are created in a matter of weeks.

  • Are Lab grown diamonds real diamonds?

    While lab grown diamonds share the same chemical composition as natural diamonds, they don't possess the rare and unique formation process that adds intrinsic value and romantic symbolism to natural diamonds nor the unique characteristics of natural diamonds.

  • Are, lab grown cheaper than natural diamonds?

    Yes, they are very much discounted compared to natural diamonds. But while they might be more affordable, natural diamonds offer a unique blend of rarity, history, and sentiment that many believe is priceless.

  • How can I tell the difference between a lab grown and a natural diamond?

    Specialised equipment and trained gemmologists can easily detect the differences. While both are beautiful, many cherish natural diamonds for the unique journey they've taken over millions of years to reach us.

    Yes, we provide this service with a nominal fees.

  • Do lab grown diamonds have resale value?

    The resale value of lab grown diamonds is still being determined, at present there is no resale market or value in second hand lab grown diamonds. Natural diamonds, on the other hand, have a long-established resale market and often hold or increase in value over time, symbolising a lasting legacy.

  • Are lab grown diamonds more greener and more eco-friendly alternative to mined diamonds?

    This is a very interesting question, as mining for diamonds, which are an incredibly rare material, involves the processing of around 200 tonnes of ore to produce 1.0ct of cut and polished diamond. However lab grown diamonds are created using extreme heat and pressure: it's no coincidence that many mines are found in the cones of extinct volcanoes! This means that to create a lab grown diamond the machines use something like 1000 kWh per carat of polished diamond produced - the same as running a 2 bedroomed house for 4 years!

  • What are environmental impacts of producing lab grown diamonds?

    While lab grown diamonds do have a smaller environmental footprint, choosing ethically mined natural diamonds ensures support for sustainable mining practices and the communities they uplift.
