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 and certified by IGI 763627020. Listed at 5 retailers as of November 1, 2026, with prices from HK$3,707 to HK$9,277, a HK$5,570 spread on the same certified stone. MOH London lists it at HK$9,277. 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.
