About this 3.03ct natural cushion diamond

This 3.03ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1548978857. Listed at 2 retailers as of October 29, 2026, with prices from €20,573 to €24,357, a €3,784 spread on the same certified stone. Blue Nile lists it at €24,357. 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.
