About this 0.77ct natural cushion diamond

This 0.77ct natural cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1558118494. Listed at 4 retailers as of November 6, 2026, with prices from £625 to £1,366, a £742 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,366. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
