About this 15.09ct lab-grown radiant diamond

This 15.09ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG830649365 or 830649365. Listed at 15 retailers as of November 1, 2026, with a 28% 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.
