About this 1.31ct natural cushion diamond

This 1.31ct natural cushion sits in the one-and-a-quarter to one-and-a-half 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 1395417930. Listed at 15 retailers as of November 4, 2026, with prices from €2,339 to €5,070, a €2,731 spread on the same certified stone. MOH London lists it at €5,070. 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.
