About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG826681497 or 826681497. Listed at 3 retailers as of November 4, 2026, with prices from £573 to £3,059, a £2,486 spread on the same certified stone. Frank Darling lists it at £3,059. 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.
