This 3.16ct 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 LG737530163 or 737530163. Listed at 23 retailers as of October 27, 2026, with prices from £544 to £2,733, a £2,190 spread on the same certified stone. Rare Carat lists it at £2,733. 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.
