About this 1.7ct lab-grown emerald diamond

This 1.7ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG657451067 or 657451067. Listed at 19 retailers as of October 27, 2026, with prices from $351 to $2,369, a $2,018 spread on the same certified stone. Brilliant Earth lists it at $2,369. 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.
