This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG685532105 or 685532105. Listed at 8 retailers as of October 27, 2026, with prices from $479 to $2,800, a $2,321 spread on the same certified stone. Do Amore Diamonds lists it at $2,800. 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.
