About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG811636247 or 811636247. Listed at 18 retailers as of October 25, 2026, with prices from £254 to £1,336, a £1,082 spread on the same certified stone. Queensmith lists it at £1,336. 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.
