This 0.99ct lab-grown emerald sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616811 or 778616811. Listed at 13 retailers as of October 29, 2026, with prices from $321 to $1,950, a $1,629 spread on the same certified stone. Brilliant Earth lists it at $1,950. 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.
