About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded I 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 2556706984. Listed at 14 retailers as of November 5, 2026, with prices from HK$3,652 to HK$16,443, a HK$12,791 spread on the same certified stone. NZ Jewellers lists it at HK$16,443. 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.
