About this 0.3ct natural heart diamond

This 0.3ct natural heart sits in the sub-half-carat band, graded D 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 1555959017. Listed at 18 retailers as of October 30, 2026, with prices from £339 to £1,425, a £1,085 spread on the same certified stone. NZ Jewellers lists it at £1,425. 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.
