About this 3.51ct natural cushion diamond

This 3.51ct natural cushion sits in the three to five carat band, graded H 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 16860130. Listed at 5 retailers as of October 31, 2026, with prices from €41,528 to €48,804, a €7,276 spread on the same certified stone. Yorxs lists it at €48,804. 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.
