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 5566454133. Listed at 10 retailers as of November 4, 2026, with prices from HK$7,728 to HK$18,763, a HK$11,034 spread on the same certified stone. MOH London lists it at HK$18,763. 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.
