About this 0.55ct natural round diamond

This 0.55ct natural round sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 754530770. Listed at 18 retailers as of November 2, 2026, with prices from £809 to £2,607, a £1,798 spread on the same certified stone. NZ Jewellers lists it at £2,607. 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.
