About this 1.7ct lab-grown emerald diamond

This 1.7ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG615387194 or 615387194. Listed at 5 retailers as of November 1, 2026, with a relatively tight 23% 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.
