About this 12.03ct lab-grown radiant diamond

This 12.03ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG747546595 or 747546595. Listed at 17 retailers as of October 26, 2026, with a 59% 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.
