This 0.66ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG786682600 or 786682600. Listed at 16 retailers as of October 26, 2026, with prices from $192 to $1,375, a $1,183 spread on the same certified stone. MOH London lists it at $1,375. 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.
