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 7518894445. Listed at 5 retailers as of October 31, 2026, with prices from £608 to £1,220, a £612 spread on the same certified stone. MOH London lists it at £1,220. 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.
