This 3.06ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG787623109 or 787623109. Listed at 15 retailers as of October 29, 2026, with prices from £682 to £4,318, a £3,635 spread on the same certified stone. Brilliant Earth lists it at £4,318. 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.
