About this 1.23ct natural cushion diamond

This 1.23ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7548694112. Listed at 7 retailers as of October 30, 2026, with prices from €1,198 to €2,253, a €1,055 spread on the same certified stone. With Clarity lists it at €2,253. 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.
