About this 5.21ct lab-grown emerald diamond

This 5.21ct lab-grown emerald sits in the over five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI. Listed at 6 retailers as of October 28, 2026, with a 117% 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.
