The real carbon math behind grown, not mined

A lab-grown diamond is carbon, arranged exactly as it is in a mined diamond. What differs is how it got that way — and that is where its footprint lives.

Where a mined diamond's footprint comes from

Mining moves a great deal of earth and rock to recover a very small amount of diamond, and it runs heavy machinery, processing plants and long supply chains to do it. The land itself is changed for decades.

Where a grown diamond's footprint comes from

A grown diamond needs no excavation. It needs energy: high pressure and high temperature (HPHT), or a carefully held plasma in a chamber (CVD), running for days or weeks while the crystal forms. So the honest answer to "how green is it?" is: it depends on the electricity. The same diamond grown on renewable power and on a coal-heavy grid can have very different footprints.

What to ask any jeweller

• Where was the diamond grown, and on what kind of power?
• Is there an independent report for the stone itself — IGI or GIA — that names it as laboratory-grown?
• Are sustainability claims backed by a named third party, not just a word on a label?

What we promise

Every Whitemoon diamond is lab-grown and independently graded, and the report travels with your piece. We would rather give you a straight answer to the questions above than a slogan.
