About this 0.77ct natural cushion diamond

This 0.77ct natural cushion sits in the just-under-one-carat band, graded F colour (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 1558091322. Listed at 13 retailers as of November 6, 2026, with prices from £1,027 to £2,300, a £1,273 spread on the same certified stone. Flawless Fine Jewelry lists it at £2,300. 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.
