About this 4ct lab-grown cushion diamond

This 4ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG750575707 or 750575707. Listed at 9 retailers as of October 25, 2026, with prices from £858 to £4,441, a £3,582 spread on the same certified stone. Do Amore Diamonds lists it at £4,441. 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.
