About this 5.26ct lab-grown cushion diamond

This 5.26ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of October 29, 2026, with prices from £3,295 to £5,091, a £1,795 spread on the same certified stone. Blue Nile lists it at £5,091. 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.
