About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded E 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 1435659441. Listed at 10 retailers as of November 6, 2026, with prices from £24,391 to £31,025, a £6,634 spread on the same certified stone. GemTrove lists it at £31,025. 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.
