About this 2.56ct lab-grown cushion diamond

This 2.56ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG741587893 or 741587893. Listed at 21 retailers as of October 28, 2026, with prices from £1,566 to £6,246, a £4,680 spread on the same certified stone. With Clarity lists it at £6,246. 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.
