0.31ct F IF Cushion Natural Diamond

About this 0.31ct natural cushion diamond

This 0.31ct natural cushion sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6541663644. Listed at 16 retailers as of November 2, 2026, with prices from $370 to $1,143, a $773 spread on the same certified stone. MOH London lists it at $1,143. 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.
