About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3515861238. Listed at 16 retailers as of October 29, 2026, with prices from £1,217 to £7,471, a £6,254 spread on the same certified stone. Do Amore Diamonds lists it at £7,471. 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.
