About this 5ct lab-grown cushion diamond

This 5ct lab-grown cushion sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837637635 or 837637635. Listed at 10 retailers as of October 30, 2026, with prices from £1,729 to £5,523, a £3,794 spread on the same certified stone. Brilliant Earth lists it at £5,523. 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.
