About this 3.06ct natural cushion diamond

This 3.06ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2245087025. Listed at 15 retailers as of November 4, 2026, with prices from £15,520 to £29,796, a £14,276 spread on the same certified stone. MOH London lists it at £29,796. 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.
