About this 0.52ct lab-grown radiant diamond

This 0.52ct lab-grown radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG407950385 or 407950385. Listed at 13 retailers as of October 28, 2026, with a 133% 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.
