The collections

The White Moon difference

Grown by light,
not torn from the earth.

A lab-grown diamond is a diamond. The same carbon, the same fire, the same forever. The only thing we leave in the ground is the cost to it.

  • 01Identical to minedChemically, optically, physically the same under any loupe.
  • 02Independently gradedEvery stone certified by IGI or GIA, never by us.
  • 03Honestly pricedThe brilliance of fine jewellery, without the old markup.

The fire on this stone genuinely stops people. No one believes it is lab-grown until I tell them.

★★★★★
Certified, beautifully made, and a third of what the high street quoted. I do not know why anyone buys mined.

They resized it for free after the proposal and sent the certificate framed. The service is the real luxury.
