About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG514249826 or 514249826. Listed at 7 retailers as of October 29, 2026, with prices from £204 to £1,569, a £1,365 spread on the same certified stone. Do Amore Diamonds lists it at £1,569. 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.
