This 0.71ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG520299947 or 520299947. Listed at 17 retailers as of October 27, 2026, with prices from £98 to £946, a £848 spread on the same certified stone. Do Amore Diamonds lists it at £946. 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.
