This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836603451 or 836603451. Listed at 12 retailers as of October 30, 2026, with prices from $1,522 to $8,197, a $6,676 spread on the same certified stone. Brilliant Earth lists it at $8,197. 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.
