We founded CARAT* London in 2003, believing that fine jewellery needed democratising and gemstones needed better provenance.

Our mission was then, as it is now, to transition the world to more sustainable gemstones.

We sold our first lab-grown gemstone in 2003, and it has taken quite some time for our relatively small industry to bloom.

   The key to our success has been developing fashionable and fine designs using quality lab-grown alternatives to mined gemstones.

 All our lab-grown diamonds, sapphire, ruby emerald, cubic zirconia and hydrothermal crystals are selected from premium rough and are cut and polished to a high specification.

We are all in a new diamond age.

A New Diamond for a New Generation.
