About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded M colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 831669276. Listed at 2 retailers as of November 1, 2026, with prices from £632 to £781, a £149 spread on the same certified stone. Yorxs lists it at £781. 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.
