About this 1.01ct lab-grown radiant diamond

This 1.01ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG835666006 or 835666006. Listed at 9 retailers as of November 4, 2026, with a 320% 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.
