This 1.27ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG816620165 or 816620165. Listed at 16 retailers as of October 26, 2026, with prices from $158 to $919, a $761 spread on the same certified stone. MOH London lists it at $919. 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.
