About this 0.31ct natural radiant diamond

This 0.31ct natural radiant sits in the sub-half-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 6511948478. Listed at 9 retailers as of October 27, 2026, with prices from HK$4,280 to HK$13,331, a HK$9,051 spread on the same certified stone. NZ Jewellers lists it at HK$13,331. 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.
