About this 1.51ct lab-grown emerald diamond

This 1.51ct lab-grown emerald sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG570349268 or 570349268. Listed at 14 retailers as of November 4, 2026, with prices from $338 to $2,900, a $2,562 spread on the same certified stone. Do Amore Diamonds lists it at $2,900. 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.
