This 5.19ct lab-grown radiant sits in the over five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG632432286 or 632432286. Listed at 12 retailers as of October 26, 2026, with prices from $2,104 to $10,023, a $7,918 spread on the same certified stone. Brilliant Earth lists it at $10,023. 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.
