About this 0.55ct lab-grown cushion diamond

This 0.55ct 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 LG838621787 or 838621787. Listed at 12 retailers as of October 30, 2026, with prices from £115 to £746, a £631 spread on the same certified stone. Reve Diamonds lists it at £746. 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.
