About this 0.5ct natural marquise diamond

This 0.5ct natural marquise 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 5546178421. Listed at 5 retailers as of November 4, 2026, with prices from HK$6,245 to HK$10,189, a HK$3,944 spread on the same certified stone. GemTrove lists it at HK$10,189. 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.
