About this 0.33ct natural round diamond

This 0.33ct natural round sits in the sub-half-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 355941015. Listed at 16 retailers as of October 26, 2026, with prices from £194 to £880, a £686 spread on the same certified stone. NZ Jewellers lists it at £880. 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.
