About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded J 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 6555812794. Listed at 20 retailers as of October 30, 2026, with prices from HK$4,098 to HK$16,570, a HK$12,472 spread on the same certified stone. NZ Jewellers lists it at HK$16,570. 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.
