This 1.91ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG712553185 or 712553185. Listed at 24 retailers as of October 30, 2026, with prices from $813 to $5,607, a $4,794 spread on the same certified stone. Brilliant Earth lists it at $5,607. 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.
