This 1.71ct 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 LG838640351 or 838640351. Listed at 11 retailers as of October 28, 2026, with prices from $656 to $2,854, a $2,198 spread on the same certified stone. MOH London lists it at $2,854. 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.
