About this 1.88ct lab-grown radiant diamond

This 1.88ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818654268 or 818654268. Listed at 21 retailers as of October 31, 2026, with a 519% 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.
