About this 3.78ct lab-grown emerald diamond

This 3.78ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG641477551 or 641477551. Listed at 17 retailers as of October 30, 2026, with a 392% 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.
