About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded E 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 1523257542. Listed at 16 retailers as of November 2, 2026, with prices from HK$7,940 to HK$30,660, a HK$22,720 spread on the same certified stone. MOH London lists it at HK$30,660. 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.
