This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG598363850 or 598363850. Listed at 16 retailers as of November 4, 2026, with prices from $325 to $1,602, a $1,277 spread on the same certified stone. MOH London lists it at $1,602. 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.
