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 1508990124. Listed at 10 retailers as of November 4, 2026, with prices from £981 to £2,557, a £1,577 spread on the same certified stone. NZ Jewellers lists it at £2,557. 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.
