This 1.88ct 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 LG608389619 or 608389619. Listed at 9 retailers as of November 2, 2026, with prices from $427 to $2,370, a $1,943 spread on the same certified stone. Do Amore Diamonds lists it at $2,370. 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.
