About this 0.55ct natural marquise diamond

This 0.55ct 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 1558631498. Listed at 11 retailers as of October 31, 2026, with prices from $2,146 to $4,213, a $2,067 spread on the same certified stone. Cape Diamonds lists it at $4,213. 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.
