About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded G 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 6565328642. Listed at 11 retailers as of November 4, 2026, with prices from HK$5,492 to HK$9,050, a HK$3,559 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$9,050. 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.
