About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407998175 or 407998175. Listed at 19 retailers as of November 2, 2026, with prices from $239 to $1,232, a $993 spread on the same certified stone. MOH London lists it at $1,232. 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.
