About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839647829 or 839647829. Listed at 16 retailers as of October 25, 2026, with prices from £137 to £808, a £672 spread on the same certified stone. Reve Diamonds lists it at £808. 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.
