About this 4.05ct lab-grown radiant diamond

This 4.05ct lab-grown radiant sits in the three to five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG758581172 or 758581172. Listed at 22 retailers as of November 1, 2026, with a 335% 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.
