About this 5.89ct lab-grown cushion diamond

This 5.89ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1505521918. Listed at 4 retailers as of October 30, 2026, with prices from £7,486 to £8,978, a £1,493 spread on the same certified stone. Kay Jewelers lists it at £8,978. 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.
