About this 5.31ct lab-grown cushion diamond

This 5.31ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2504427392. Listed at 4 retailers as of October 30, 2026, with prices from £5,769 to £6,926, a £1,157 spread on the same certified stone. Kay Jewelers lists it at £6,926. 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.
