About this 3.02ct natural cushion diamond

This 3.02ct 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 3515789511. Listed at 13 retailers as of November 2, 2026, with prices from £19,892 to £32,568, a £12,676 spread on the same certified stone. MOH London lists it at £32,568. 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.
