About this 0.31ct natural round diamond

This 0.31ct natural round sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2566505318. Listed at 17 retailers as of October 26, 2026, with prices from $448 to $1,693, a $1,245 spread on the same certified stone. NZ Jewellers lists it at $1,693. 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.
