About this 1.18ct lab-grown emerald diamond

This 1.18ct lab-grown emerald sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG612329329 or 612329329. Listed at 6 retailers as of October 29, 2026, with prices from $331 to $1,046, a $715 spread on the same certified stone. MOH London lists it at $1,046. 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.
