About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6372933464. Listed at 15 retailers as of November 6, 2026, with prices from €1,779 to €2,743, a €965 spread on the same certified stone. Washington Diamond lists it at €2,743. 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.
