About this 1.06ct lab-grown cushion diamond

This 1.06ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG668407387 or 668407387. Listed at 10 retailers as of October 27, 2026, with prices from £205 to £1,302, a £1,097 spread on the same certified stone. Do Amore Diamonds lists it at £1,302. 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.
