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 IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG638491370 or 638491370. Listed at 25 retailers as of October 30, 2026, with prices from $383 to $3,228, a $2,845 spread on the same certified stone. Brilliant Earth lists it at $3,228. 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.
