About this 2.15ct lab-grown cushion diamond

This 2.15ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG659430617 or 659430617. Listed at 4 retailers as of October 28, 2026, with prices from £1,171 to £3,725, a £2,553 spread on the same certified stone. Kay Jewelers lists it at £3,725. 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.
