This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG816607609 or 816607609. Listed at 18 retailers as of October 25, 2026, with prices from $470 to $2,604, a $2,134 spread on the same certified stone. Queensmith lists it at $2,604. 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.
