Loose stones
Cut at the source, matched for production.
We supply the stones we grow and cut ourselves. Lab-grown diamonds from our own HPHT and CVD production, moissanite cut in-house, and coloured gemstones — all calibrated and certified for brands that do their own setting.
Buying at source level means better pricing and supply you can plan around, with grading reports per stone or per batch.
Every stone is clearly labelled — lab-grown diamonds as lab-grown, moissanite as moissanite.
