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.

Beyond the white diamond
The art of gemstones
Can your diamond match
your personal style?
Absolutely. Choose the shape, the setting, the metal and the stone. We craft it to order, finish it by hand, and make it only for you.
Loved by thousands
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.
