This 1.51ct lab-grown emerald sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG591367466 or 591367466. Listed at 16 retailers as of October 30, 2026, with prices from $224 to $1,417, a $1,193 spread on the same certified stone. Taylor and Hart lists it at $1,417. 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.
