This 4.48ct lab-grown emerald sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG828680590 or 828680590. Listed at 15 retailers as of November 3, 2026, with prices from $9,750 to $41,240, a $31,490 spread on the same certified stone. With Clarity lists it at $41,240. 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.
