About this 0.51ct natural heart diamond

This 0.51ct 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 7546085420. Listed at 14 retailers as of November 2, 2026, with prices from HK$3,515 to HK$9,914, a HK$6,399 spread on the same certified stone. MOH London lists it at HK$9,914. 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.
