This 1.28ct 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 LG843661173 or 843661173. Listed at 12 retailers as of November 2, 2026, with prices from $239 to $1,415, a $1,176 spread on the same certified stone. MOH London lists it at $1,415. 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.
