About this 3.01ct natural cushion diamond

This 3.01ct 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 2557555789. Listed at 3 retailers as of November 5, 2026, with prices from £14,578 to £17,476, a £2,899 spread on the same certified stone. Blue Nile lists it at £17,476. 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.
