This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG628451220 or 628451220. Listed at 19 retailers as of October 28, 2026, with prices from $307 to $2,160, a $1,853 spread on the same certified stone. Brilliant Earth lists it at $2,160. 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.
