About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded F 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 5231946108. Listed at 6 retailers as of November 4, 2026, with prices from HK$11,623 to HK$18,782, a HK$7,159 spread on the same certified stone. MOH London lists it at HK$18,782. 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.
