This 1.29ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843608148 or 843608148. Listed at 15 retailers as of November 4, 2026, with prices from £121 to £704, a £582 spread on the same certified stone. MOH London lists it at £704. 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.
