Learn More About idem Diamonds

Lab-grown diamonds are chemically, optically,
and physically identical to mined diamonds—they’re real diamonds. The only
difference is how they’re created: in a controlled lab environment rather than
mined from Earth. You get the same 4 Cs (cut, colour, clarity, carat),
certified by GIA or IGI, with significantly lower environmental impact and
conflict-free sourcing.



  • Eco-friendly & ethical: No
    destructive mining, smaller carbon footprint, and guaranteed conflict-free.
  • Affordable luxury: Up
    to 70% less expensive due to streamlined production and no retail markups.
  • Certified quality:
    Every diamond comes with an official GIA or IGI report

You’ll find a wide selection across these
categories:

  • Engagement & wedding rings
    (Solitaire, Halo, Hidden Halo, Three-Stone, Band Sets)
  • Wedding bands (for
    men & women, in various metals and finishes)
  • Fine jewellery
    (Diamond bracelets, necklaces, earrings, fashion rings, eternity rings,
    stacking rings)
