About this 3.06ct lab-grown radiant diamond

This 3.06ct lab-grown radiant sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG476177997 or 476177997. Listed at 18 retailers as of November 1, 2026, with a 305% 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.
