This 3.08ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG645443395 or 645443395. Listed at 19 retailers as of November 1, 2026, with prices from £625 to £4,426, a £3,800 spread on the same certified stone. Do Amore Diamonds lists it at £4,426. 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.
