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 standard cut grade and certified by IGI LG628464261 or 628464261. Listed at 20 retailers as of October 27, 2026, with prices from £115 to £746, a £631 spread on the same certified stone. Brilliant Earth lists it at £746. 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.
