About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded M colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6217171779. Listed at 2 retailers as of November 5, 2026, with prices from $690 to $863, a $173 spread on the same certified stone. Yorxs lists it at $863. 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.
