About this 5.04ct lab-grown radiant diamond

This 5.04ct lab-grown radiant sits in the over five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG622400141 or 622400141. Listed at 15 retailers as of October 31, 2026, with a 485% 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.
