About this 0.91ct natural round diamond

This 0.91ct natural round sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA. Listed at 4 retailers as of October 31, 2026, with prices from £5,146 to £8,202, a £3,056 spread on the same certified stone. The Diamond Guys lists it at £8,202. 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.
