About this 0.91ct lab-grown radiant diamond

This 0.91ct lab-grown radiant sits in the just-under-one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407950376 or 407950376. Listed at 11 retailers as of November 4, 2026, with a 321% 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.
