About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-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 6491020554. Listed at 11 retailers as of November 6, 2026, with prices from HK$7,924 to HK$19,638, a HK$11,715 spread on the same certified stone. MOH London lists it at HK$19,638. 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.
