This 1.81ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG841625591 or 841625591. Listed at 8 retailers as of October 31, 2026, with prices from $458 to $3,070, a $2,612 spread on the same certified stone. Brilliant Earth lists it at $3,070. 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.
