This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG657463070 or 657463070. Listed at 18 retailers as of November 1, 2026, with prices from $427 to $2,008, a $1,581 spread on the same certified stone. Reve Diamonds lists it at $2,008. 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.
