About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG615363762 or 615363762. Listed at 8 retailers as of October 27, 2026, with prices from £147 to £1,136, a £990 spread on the same certified stone. Do Amore Diamonds lists it at £1,136. 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.
