About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555310256. Listed at 18 retailers as of November 2, 2026, with prices from €1,249 to €2,799, a €1,550 spread on the same certified stone. MOH London lists it at €2,799. 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.
