About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG602314113 or 602314113. Listed at 17 retailers as of November 6, 2026, with prices from £102 to £1,053, a £951 spread on the same certified stone. Do Amore Diamonds lists it at £1,053. 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.
