About this 0.55ct natural round diamond

This 0.55ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6541020560. Listed at 6 retailers as of November 4, 2026, with prices from £397 to £1,349, a £952 spread on the same certified stone. NZ Jewellers lists it at £1,349. 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.
