This 3.2ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG845617016 or 845617016. Listed at 17 retailers as of October 28, 2026, with prices from £454 to £2,823, a £2,369 spread on the same certified stone. Rare Carat lists it at £2,823. 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.
