This 1.88ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG752572737 or 752572737. Listed at 12 retailers as of November 1, 2026, with prices from $238 to $1,265, a $1,027 spread on the same certified stone. Rare Carat lists it at $1,265. 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.
