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 E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836690427 or 836690427. Listed at 14 retailers as of October 29, 2026, with a 386% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
