About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6565104737. Listed at 9 retailers as of October 29, 2026, with prices from $922 to $1,748, a $826 spread on the same certified stone. Sky Moon Diamonds lists it at $1,748. 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.
