Natural diamonds

Salt-and-pepper natural diamonds have found a steady niche

Heavily included natural diamonds once sold mainly as industrial rough are now a small but consistent request category for one-of-a-kind jewellery, with their own pricing logic separate from clarity-graded stones.

Heavily included natural diamonds, once sold mainly as industrial rough, are now a small but consistent request category for one-of-a-kind jewellery.

  • Salt-and-pepper stones are prized for the pattern of inclusions itself rather than judged against the standard clarity scale, so a stone that would grade poorly on the 4Cs can carry a premium if its inclusions are visually striking.
  • Demand is concentrated among buyers wanting a natural stone with an unrepeatable appearance, often for a non-traditional engagement ring or a statement piece.
  • Pricing follows its own logic: cut and the visual balance of the inclusion pattern matter more than carat weight or colour, which makes each stone closer to a one-off than a graded commodity.

Because these stones don't fit neatly into a spec sheet, buying one is closer to buying a piece of art than ordering to a specification. If a salt-and-pepper stone is of interest, contact us to see current pieces in hand rather than searching by the standard 4Cs filters.
