About this 1.22ct lab-grown cushion diamond

This 1.22ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG816607623 or 816607623. Listed at 19 retailers as of October 27, 2026, with prices from £301 to £1,592, a £1,292 spread on the same certified stone. Queensmith lists it at £1,592. 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.
