About this 1.73ct natural cushion diamond

This 1.73ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1438760678. Listed at 8 retailers as of October 28, 2026, with prices from €2,869 to €4,137, a €1,268 spread on the same certified stone. Yorxs lists it at €4,137. 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.
