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 I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG539203633 or 539203633. Listed at 11 retailers as of October 26, 2026, with prices from $392 to $1,947, a $1,555 spread on the same certified stone. MOH London lists it at $1,947. 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.
