About this 1.2ct natural cushion diamond

This 1.2ct 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 2151597618. Listed at 7 retailers as of November 1, 2026, with prices from €1,706 to €2,698, a €992 spread on the same certified stone. 77 Diamonds lists it at €2,698. 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.
