About this 3.03ct natural cushion diamond

This 3.03ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556396915. Listed at 5 retailers as of November 2, 2026, with prices from £14,439 to £22,270, a £7,831 spread on the same certified stone. MOH London lists it at £22,270. 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.
