About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6451330634. Listed at 18 retailers as of November 1, 2026, with prices from €2,915 to €6,694, a €3,779 spread on the same certified stone. Diamond Quarter lists it at €6,694. 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.
