This 1.62ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG629405819 or 629405819. Listed at 10 retailers as of October 31, 2026, with prices from $437 to $2,819, a $2,381 spread on the same certified stone. Brilliant Earth lists it at $2,819. 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.
