About this 3.02ct lab-grown cushion diamond

This 3.02ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG738519211 or 738519211. Listed at 12 retailers as of November 6, 2026, with prices from £332 to £3,317, a £2,985 spread on the same certified stone. Brilliant Earth lists it at £3,317. 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.
