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 standard cut grade and certified by IGI LG839640540 or 839640540. Listed at 7 retailers as of November 1, 2026, with prices from €175 to €921, a €746 spread on the same certified stone. MOH London lists it at €921. 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.
