About this 2.1ct lab-grown cushion diamond

This 2.1ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG516238411 or 516238411. Listed at 7 retailers as of October 28, 2026, with prices from £346 to £1,034, a £687 spread on the same certified stone. Rare Carat lists it at £1,034. 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.
