About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1378934020. Listed at 15 retailers as of October 31, 2026, with prices from €1,722 to €2,484, a €762 spread on the same certified stone. Yorxs lists it at €2,484. 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.
