About this 6.42ct lab-grown radiant diamond

This 6.42ct lab-grown radiant sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG842613775 or 842613775. Listed at 16 retailers as of October 30, 2026, with a 301% 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.
