About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559260352. Listed at 2 retailers as of November 3, 2026, with prices from £12,134 to £14,560, a £2,426 spread on the same certified stone. Blue Nile lists it at £14,560. 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.
