This 1.66ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG843604942 or 843604942. Listed at 15 retailers as of October 31, 2026, with prices from $387 to $4,540, a $4,153 spread on the same certified stone. Brilliant Earth lists it at $4,540. 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.
