About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG839611403 or 839611403. Listed at 17 retailers as of October 27, 2026, with prices from £137 to £834, a £696 spread on the same certified stone. Brilliant Earth lists it at £834. 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.
