This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG570337149 or 570337149. Listed at 2 retailers as of October 30, 2026, with prices from $869 to $1,143, a $274 spread on the same certified stone. The Diamond Guys lists it at $1,143. 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.
