This 1.98ct lab-grown marquise 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 LG835663538 or 835663538. Listed at 3 retailers as of October 31, 2026, with prices from $542 to $2,020, a $1,478 spread on the same certified stone. Brilliance lists it at $2,020. 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.
