About this 3.18ct lab-grown emerald diamond

This 3.18ct 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 LG849629603 or 849629603. Listed at 8 retailers as of October 30, 2026, with prices from $2,140 to $8,021, a $5,882 spread on the same certified stone. Taylor and Hart lists it at $8,021. 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.
