About this 1.57ct lab-grown emerald diamond

This 1.57ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG713526366 or 713526366. Listed at 12 retailers as of November 1, 2026, with prices from $352 to $2,460, a $2,108 spread on the same certified stone. Brilliant Earth lists it at $2,460. 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.
