About this 1.06ct natural cushion diamond

This 1.06ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555490385. Listed at 4 retailers as of November 2, 2026, with prices from €950 to €1,885, a €935 spread on the same certified stone. MOH London lists it at €1,885. 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.
