About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded D 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 6552750062. Listed at 14 retailers as of October 31, 2026, with prices from $1,479 to $3,262, a $1,783 spread on the same certified stone. Flawless Fine Jewelry lists it at $3,262. 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.
