About this 1.51ct lab-grown emerald diamond

This 1.51ct 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 LG620416770 or 620416770. Listed at 6 retailers as of October 29, 2026, with prices from $344 to $1,107, a $763 spread on the same certified stone. MOH London lists it at $1,107. 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.
