About this 3.99ct lab-grown radiant diamond

This 3.99ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG781625335 or 781625335. Listed at 4 retailers as of October 28, 2026, with a 79% 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.
