About this 0.55ct natural radiant diamond

This 0.55ct natural radiant 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 and certified by IGI 815625361. Listed at 11 retailers as of November 5, 2026, with prices from £356 to £1,541, a £1,185 spread on the same certified stone. NZ Jewellers lists it at £1,541. 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.
