About this 0.5ct natural round diamond

This 0.5ct 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 1553380129. Listed at 5 retailers as of November 5, 2026, with prices from $394 to $740, a $346 spread on the same certified stone. RockHer lists it at $740. 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.
