About this 3.17ct lab-grown cushion diamond

This 3.17ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG651483013 or 651483013. Listed at 6 retailers as of November 5, 2026, with prices from £605 to £1,605, a £1,000 spread on the same certified stone. MOH London lists it at £1,605. 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.
