This 1.51ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG818681789 or 818681789. Listed at 17 retailers as of November 1, 2026, with prices from $373 to $1,886, a $1,513 spread on the same certified stone. Brilliance lists it at $1,886. 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.
