About this 1ct lab-grown cushion diamond

This 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 LG828686852 or 828686852. Listed at 2 retailers as of November 4, 2026, with prices from £130 to £201, a £71 spread on the same certified stone. Loose Grown Diamond lists it at £201. 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.
