About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-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 5231928046. Listed at 14 retailers as of October 28, 2026, with prices from $650 to $1,448, a $798 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,448. 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.
