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.
A lab-grown stone of this exact specification runs about 95% below the natural equivalent. If the origin is not important to you, that is the single largest saving available on this page.
Stepping up to 2ct costs about 113% more. Buying just under a round carat weight is the usual way to capture most of the visual size without paying the full jump.
Dropping to 1ct saves about 73%, and the difference in visible diameter is small enough that most people cannot pick it without the two stones side by side.

How this is measured
Measured on October 29, 2026 from 357 certificated diamonds between 1.5 and 1.69 carat, carrying 2714 current listings across 25 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.
