Loose diamonds cut to your spec

For buyers who grade their own stones, we cut loose diamonds to their own specification, without the cost of a certificate they don't need.

Who it's for

Jewellers and manufacturers who know exactly what they want and are confident grading it themselves.

If you'd rather have a lab report, choose from our certified natural or lab-grown stock instead.

How grading works

These stones are graded in-house and sold without an independent lab report. We describe each stone's shape, weight, colour and clarity as we grade it, and you can check it on arrival.

How an order runs

  1. Your spec

    Shape, size or weight, colour, clarity, cut and quantity.

  2. Quote and deposit

    We confirm price and timeline. A 50% deposit starts the work.

  3. Cut and deliver

    Stones are cut, graded and shipped. Cut-to-spec stones can't be returned unless faulty or not as described.
