About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6401052892. Listed at 3 retailers as of November 2, 2026, with prices from £1,510 to £2,428, a £917 spread on the same certified stone. MOH London lists it at £2,428. 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.
