About this 1.5ct lab-grown emerald diamond

This 1.5ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG668473379 or 668473379. Listed at 20 retailers as of November 1, 2026, with prices from $304 to $3,022, a $2,718 spread on the same certified stone. Brilliant Earth lists it at $3,022. 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.
