This 1.98ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG651478916 or 651478916. Listed at 9 retailers as of October 29, 2026, with prices from $730 to $4,270, a $3,540 spread on the same certified stone. Brilliant Earth lists it at $4,270. 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.
