About this 1.36ct lab-grown cushion diamond

This 1.36ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG530225163 or 530225163. Listed at 11 retailers as of November 4, 2026, with prices from £320 to £1,701, a £1,381 spread on the same certified stone. Do Amore Diamonds lists it at £1,701. 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.
