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 27, 2026, with prices from $1,310 to $2,486, a $1,175 spread on the same certified stone. Sky Moon Diamonds lists it at $2,486. 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.
