About us

A manufacturer, not a middleman.

PSM Jewels is a vertically integrated maker of natural and lab-grown diamonds and fine jewelry — rough to finished piece, under one roof.

Who we are

Decades on the wheel.

We are a B2B manufacturer. Jewelers, designers, brands and wholesalers come to us for consistent make, accurate grading and dependable delivery — whether that’s a single bespoke stone or a recurring production run.

Because sourcing, planning, cutting, grading and setting all happen in the same building, nothing gets lost in a handoff. The person who planned the stone is down the corridor from the person who set it.

The floor

Five stages, one building.

Nothing is subcontracted. That is the whole argument for buying from us rather than from a trader.

  1. 01

    Sourcing

    We buy natural rough directly and grow our own lab material, taking only what meets our standards for yield, color and clarity.

  2. 02

    Planning

    Every stone is 3D-scanned and mapped before a facet is touched. Planning is where the money is made or lost.

  3. 03

    Cutting

    Master cutters shape and polish on our own wheels — classic shapes and bespoke commissions alike.

  4. 04

    Grading

    Our in-house gemmological lab pre-grades everything; final certification is always issued independently.

  5. 05

    Jewelry

    CAD, casting, setting and finishing for private-label and OEM programs.

How we work

Four things we hold to.

  • No middlemen

    You deal with the people who cut the stone. Questions about make, yield or grading get answered by the person who did the work.

  • Say the yield out loud

    If a shape wastes half the rough, we tell you before you commit — not after the invoice.

  • Segregated by default

    Natural and lab-grown never share a line, a tray or a document. Provenance is not something we reconstruct later.

  • Consistency over volume

    Repeat programs are judged on whether run three matches run one. That's the whole business.

  • Planning
  • The bench
