About this 0.81ct natural radiant diamond

This 0.81ct natural radiant 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 1559739100. Listed at 4 retailers as of November 1, 2026, with prices from £1,262 to £1,627, a £364 spread on the same certified stone. GemTrove lists it at £1,627. 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.
