About this 1.41ct lab-grown cushion diamond

This 1.41ct 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 LG591338790 or 591338790. Listed at 3 retailers as of November 5, 2026, with prices from £659 to £906, a £247 spread on the same certified stone. Kay Jewelers lists it at £906. 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.
