This 1.99ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG651478910 or 651478910. Listed at 9 retailers as of October 29, 2026, with prices from $614 to $3,810, a $3,196 spread on the same certified stone. Brilliant Earth lists it at $3,810. 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.
