This 3.08ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG647474920 or 647474920. Listed at 14 retailers as of October 29, 2026, with prices from £536 to £4,247, a £3,711 spread on the same certified stone. Do Amore Diamonds lists it at £4,247. 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.
