About this 0.57ct lab-grown cushion diamond

This 0.57ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG842606071 or 842606071. Listed at 13 retailers as of October 30, 2026, with prices from £95 to £881, a £787 spread on the same certified stone. MOH London lists it at £881. 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.
