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 VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG707528595 or 707528595. Listed at 15 retailers as of October 29, 2026, with prices from £437 to £3,724, a £3,287 spread on the same certified stone. Brilliant Earth lists it at £3,724. 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.
