About this 1.56ct lab-grown radiant diamond

This 1.56ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG646445839 or 646445839. Listed at 24 retailers as of October 27, 2026, with a 429% 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.
