About this 3.13ct lab-grown cushion diamond

This 3.13ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG652419203 or 652419203. Listed at 6 retailers as of October 29, 2026, with prices from £649 to £3,336, a £2,687 spread on the same certified stone. Brilliant Earth lists it at £3,336. 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.
