This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG644482160 or 644482160. Listed at 4 retailers as of October 30, 2026, with prices from $1,120 to $1,490, a $371 spread on the same certified stone. Kay Jewelers lists it at $1,490. 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.
