About this 0.66ct natural cushion diamond

This 0.66ct natural cushion sits in the half to three-quarter carat band, graded G 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 6551147487. Listed at 21 retailers as of November 1, 2026, with prices from $845 to $2,210, a $1,365 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,210. 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.
