This 1.49ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG841661569 or 841661569. Listed at 12 retailers as of October 27, 2026, with prices from $220 to $1,570, a $1,350 spread on the same certified stone. Brilliant Earth lists it at $1,570. 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.
