About this 4.01ct lab-grown emerald diamond

This 4.01ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG718509173 or 718509173. Listed at 19 retailers as of October 26, 2026, with a 143% 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.
