This 1.02ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG794602979 or 794602979. Listed at 13 retailers as of October 25, 2026, with prices from $235 to $1,463, a $1,229 spread on the same certified stone. Reve Diamonds lists it at $1,463. 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.
