About this 4.06ct natural cushion diamond

This 4.06ct natural cushion sits in the three to five carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2245033794. Listed at 5 retailers as of November 1, 2026, with prices from £39,209 to £48,753, a £9,544 spread on the same certified stone. Ritani lists it at £48,753. 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.
