This 3ct lab-grown emerald sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG432012462 or 432012462. Listed at 10 retailers as of November 4, 2026, with prices from $2,500 to $16,587, a $14,087 spread on the same certified stone. MOH London lists it at $16,587. 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.
