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 4, 2026, with prices from $626 to $4,376, a $3,750 spread on the same certified stone. Brilliant Earth lists it at $4,376. 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.
