About this 12.56ct lab-grown radiant diamond

This 12.56ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG771603875 or 771603875. Listed at 26 retailers as of November 2, 2026, with a 730% 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.
