About this 0.31ct natural heart diamond

This 0.31ct 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 7563488084. Listed at 13 retailers as of October 30, 2026, with prices from £419 to £1,377, a £958 spread on the same certified stone. NZ Jewellers lists it at £1,377. 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.
