About this 3.16ct lab-grown cushion diamond

This 3.16ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG516249708 or 516249708. Listed at 3 retailers as of October 30, 2026, with prices from £666 to £2,264, a £1,599 spread on the same certified stone. The Diamond Guys lists it at £2,264. 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.
