About this 0.66ct lab-grown cushion diamond

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 LG644420726 or 644420726. Listed at 11 retailers as of November 1, 2026, with prices from $147 to $1,360, a $1,213 spread on the same certified stone. MOH London lists it at $1,360. 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.
