Reading this specification
VS1 is the usual value sweet spot. Inclusions need 10x magnification to find and the stone is eye-clean in almost every case, so paying up for a VVS grade buys wording on the report rather than a visible change.
D is graded colorless, and D, E and F are not distinguishable from one another once mounted. The premium here is for rarity, not for anything a wearer will see.
A round brilliant returns more light than any other cut and hides both warmth and small inclusions better than a step cut, so grades that would be marginal elsewhere are usually safe in this shape.
The 279% spread on this specification is unusually wide, which means the retailer you choose matters more than any single grade on the report.

How this is measured
Measured on October 29, 2026 from 29166 certificated diamonds between 1 and 1.14 carat, carrying 180055 current listings across 24 retailers. Each stone with a recently confirmed price contributes the cheapest price we last saw for it, so the distribution reflects what a buyer comparing retailers would actually pay. These figures summarize many stones, so they carry the day they were measured rather than the date of any one listing.
Certificated stones with a current listed price only, and every price figure uses only prices we confirmed recently. Uncertificated inventory is excluded because its grades cannot be verified against a laboratory report.
