This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG843693251 or 843693251. Listed at 15 retailers as of October 30, 2026, with prices from $406 to $2,048, a $1,641 spread on the same certified stone. Brilliance lists it at $2,048. 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.
