About this 0.53ct natural round diamond

This 0.53ct 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 6555305632. Listed at 11 retailers as of November 6, 2026, with prices from £421 to £738, a £317 spread on the same certified stone. Frank Darling lists it at £738. 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.
