About this 0.64ct natural heart diamond

This 0.64ct natural heart sits in the half to three-quarter carat band, graded I colour (near-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 1545712115. Listed at 13 retailers as of November 5, 2026, with prices from £475 to £1,995, a £1,520 spread on the same certified stone. NZ Jewellers lists it at £1,995. 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.
