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 E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG564387095 or 564387095. Listed at 17 retailers as of November 6, 2026, with a 862% 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.
