About this 0.92ct lab-grown cushion diamond

This 0.92ct lab-grown cushion sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG520297534 or 520297534. Listed at 12 retailers as of October 30, 2026, with prices from £128 to £1,105, a £976 spread on the same certified stone. Do Amore Diamonds lists it at £1,105. 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.
