This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG823695036 or 823695036. Listed at 21 retailers as of October 30, 2026, with prices from $1,123 to $5,378, a $4,255 spread on the same certified stone. Brilliant Earth lists it at $5,378. 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.
