About this 1.53ct natural cushion diamond

This 1.53ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 6551483923. Listed at 4 retailers as of November 2, 2026, with prices from €3,169 to €5,741, a €2,572 spread on the same certified stone. MOH London lists it at €5,741. 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.
