This 1.63ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG741531006 or 741531006. Listed at 20 retailers as of October 28, 2026, with prices from $329 to $2,855, a $2,526 spread on the same certified stone. Brilliant Earth lists it at $2,855. 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.
