About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2554977752. Listed at 17 retailers as of November 1, 2026, with prices from $2,110 to $5,053, a $2,943 spread on the same certified stone. MOH London lists it at $5,053. 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.
