About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2151022020. Listed at 4 retailers as of November 5, 2026, with prices from €2,093 to €3,149, a €1,056 spread on the same certified stone. Cape Diamonds lists it at €3,149. 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.
