About this 0.7ct natural marquise diamond

This 0.7ct natural marquise sits in the half to three-quarter carat band, graded I 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. Listed at 3 retailers as of November 6, 2026, with prices from $2,592 to $3,199, a $607 spread on the same certified stone. Blue Nile lists it at $3,199. 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.
