About this 4.06ct lab-grown radiant diamond

This 4.06ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG764660729 or 764660729. Listed at 16 retailers as of October 29, 2026, with a 263% 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.
