About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-carat band, graded E 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 2517548835. Listed at 15 retailers as of October 29, 2026, with prices from £476 to £1,749, a £1,273 spread on the same certified stone. NZ Jewellers lists it at £1,749. 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.
