About this 0.7ct lab-grown radiant diamond

This 0.7ct 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 LG528232211 or 528232211. Listed at 16 retailers as of October 27, 2026, with prices from £98 to £939, a £841 spread on the same certified stone. Do Amore Diamonds lists it at £939. 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.
