Natural Diamond Jewelry

Mined natural diamonds, graded on the same 4Cs scale as lab-grown stones. The IMPERVORA range here is deliberately small and rotates with what is available at grade, so if you do not see the combination of shape, carat and colour you want, ask – the wider Stuller diamond catalog can be searched on your behalf through the Jewelry Showcase or by the concierge. Comparing the two stone types first? Read natural vs lab-grown diamonds.

Natural Diamonds in This Collection

Natural diamonds formed in the earth over geological time and were brought near the surface by volcanic activity. Every one is slightly different, and the inclusions inside a natural stone are a record of how it grew — which is why two stones with the same clarity grade can look quite unalike under magnification.

This is a deliberately small selection. Most of the diamond jewelry stocked on this site uses lab-grown stones, which offer more size and clarity for the same outlay. The natural stones are here for buyers who specifically want a mined diamond, whether for its rarity, its record of secondhand value, or simply because it matters to them where the stone came from.

Where a piece carries an independent grading report, the laboratory and the grades are stated in the product description. If the selection here does not include what you are looking for, the Jewelry Showcase opens a far larger inventory of loose natural diamonds and settings than is stocked on this site.
