About this 1.52ct lab-grown radiant diamond

This 1.52ct lab-grown radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG512220499 or 512220499. Listed at 16 retailers as of October 29, 2026, with a 81% 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.
