This 3.06ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG598370855 or 598370855. Listed at 14 retailers as of October 31, 2026, with prices from £392 to £3,105, a £2,713 spread on the same certified stone. Do Amore Diamonds lists it at £3,105. 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.
