About this 1.5ct lab-grown emerald diamond

This 1.5ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG616423547 or 616423547. Listed at 23 retailers as of October 30, 2026, with prices from $363 to $4,128, a $3,765 spread on the same certified stone. Brilliant Earth lists it at $4,128. 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.
