About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-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 7566545432. Listed at 7 retailers as of October 27, 2026, with prices from £416 to £618, a £202 spread on the same certified stone. Wholesale Diamonds Direct lists it at £618. 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.
