About this 1ct lab-grown radiant diamond
This 1ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG638428908 or 638428908. Listed at 8 retailers as of October 29, 2026, with a 237% 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.
