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 G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG570363621 or 570363621. Listed at 12 retailers as of November 2, 2026, with prices from $241 to $1,401, a $1,159 spread on the same certified stone. MOH London lists it at $1,401. 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.
