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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231837520. Listed at 8 retailers as of November 4, 2026, with prices from £18,424 to £31,521, a £13,097 spread on the same certified stone. MOH London lists it at £31,521. 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.
