About this 1.21ct lab-grown emerald diamond

This 1.21ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG649405838 or 649405838. Listed at 9 retailers as of October 26, 2026, with prices from $345 to $1,106, a $761 spread on the same certified stone. MOH London lists it at $1,106. 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.
