About this 3.3ct lab-grown cushion diamond

This 3.3ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG603358563 or 603358563. Listed at 10 retailers as of October 29, 2026, with prices from £590 to £3,127, a £2,538 spread on the same certified stone. Do Amore Diamonds lists it at £3,127. 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.
