About this 3.2ct lab-grown cushion diamond

This 3.2ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799679825 or 799679825. Listed at 16 retailers as of October 29, 2026, with prices from £452 to £3,418, a £2,967 spread on the same certified stone. Brilliant Earth lists it at £3,418. 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.
