About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG436046098 or 436046098. Listed at 11 retailers as of October 31, 2026, with a 154% 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.
