About this 0.52ct lab-grown cushion diamond

This 0.52ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG620494561 or 620494561. Listed at 6 retailers as of October 29, 2026, with prices from £177 to £658, a £481 spread on the same certified stone. MOH London lists it at £658. 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.
