Skydiamond grows its diamonds from carbon pulled out of the air, a process Imperial College London assessed as cutting emissions by 99.79 percent against a mined carat. The company is based in the Cotswolds with a London showroom, and delivery is free across the UK. If you're ordering to Zurich, confirm international delivery with their team first, since the site leads with UK shipping.
