About this 0.66ct natural cushion diamond

This 0.66ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2231034649. Listed at 6 retailers as of November 4, 2026, with prices from $1,153 to $1,875, a $722 spread on the same certified stone. MOH London lists it at $1,875. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
