About this 1.57ct lab-grown radiant diamond

This 1.57ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG807612617 or 807612617. Listed at 20 retailers as of October 26, 2026, with a 397% 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.
