Reading this specification
VS2 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.
G is near-colorless and faces up white in most shapes and settings, which is why this part of the scale is the most common value recommendation.
The 345% 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 November 1, 2026 from 197 certificated diamonds between 1.5 and 1.69 carat, carrying 898 current listings across 16 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.
