About this 1.1ct lab-grown cushion diamond

This 1.1ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG688518344 or 688518344. Listed at 10 retailers as of October 30, 2026, with prices from £286 to £1,399, a £1,113 spread on the same certified stone. Taylor and Hart lists it at £1,399. 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.
