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.
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 1.5ct costs about 133% 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 0.75ct saves about 55%, 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 1953 certificated diamonds between 1 and 1.14 carat, carrying 12344 current listings across 32 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.
