About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 7566721406. Listed at 8 retailers as of November 2, 2026, with prices from $1,023 to $2,770, a $1,747 spread on the same certified stone. NZ Jewellers lists it at $2,770. 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.
