WHO WE ARE

A Vertically Integrated Atelier, Not a Trading Middleman

  • Prime Lab Atelier is a lab-grown diamond and colored gemstone manufacturer serving retailers, designers and private-label brands across North America. From stone selection to CAD design, casting, setting and final polish, every step happens inside our own atelier — so quality never depends on a third party.
  • We built this company on one belief: a small jewelry business should be able to source overseas with the same confidence as a big-box retailer. Clear specs, written guarantees, certified stones, and one person who answers within 24 hours.
  • Every piece reflects our commitment to sustainable luxury and long-term partnerships.

How We Make It

The Stone Part & The Jewelry Part

  • The Stone Part

    Our lab-grown diamonds are sourced as IGI-certified rough and finished stones across all popular shapes; colored gemstones — emerald, ruby, sapphire and padparadscha — are grown and cut to calibrated specs. Every certified stone ships with a report number that matches its paperwork.

  • The Jewelry Part

    Our in-house manufacturing covers CAD design, casting, stone setting, polishing and finishing — handled entirely by experienced professionals in our Panyu atelier. Controlling every step lets us hold tolerance, keep lead times honest, and scale with you.
