About this 5.08ct lab-grown cushion diamond

This 5.08ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG638464106 or 638464106. Listed at 7 retailers as of October 29, 2026, with a 200% 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.
