About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6552034892. Listed at 12 retailers as of November 2, 2026, with prices from $719 to $1,316, a $597 spread on the same certified stone. Frank Darling lists it at $1,316. 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.
