This 1.55ct 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 very-good cut grade and certified by IGI LG841604510 or 841604510. Listed at 8 retailers as of October 31, 2026, with prices from $360 to $2,090, a $1,730 spread on the same certified stone. Brilliant Earth lists it at $2,090. 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.
