Lab-Grown Diamond Jewelry Manufacturers

We are manufacturers — not resellers. Our own cutting, polishing and setting facility produces finished lab-grown diamond jewelry, loose stones and custom pieces for trade buyers worldwide.

  • Finished jewelry

    Rings, earrings, pendants, bracelets and bands in 14K & 18K gold, sterling silver and platinum.

  • Loose diamonds

    Lab-grown loose stones in every size and every shape, IGI certified on request.

  • Fancy colour diamonds

    Yellow, pink, blue and green lab-grown fancies, matched to your specification.

  • Custom orders

    Send a photograph or a sketch. We return a CAD for approval, then the finished piece in gold, silver or platinum.

How we work

  • Made to order only. Every piece is produced against your order — nothing is shelf stock, so carat weight, colour, clarity, metal and size are yours to specify.
  • 10–12 business days from order confirmation to dispatch.
  • Custom work starts with your image or drawing; you approve the CAD before we cut a single stone.
