About this 1.64ct lab-grown emerald diamond

This 1.64ct lab-grown emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and I1 clarity (included) and certified by GIA 5231172737. Listed at 3 retailers as of October 30, 2026, with a relatively tight 3% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
