About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7413636707. Listed at 11 retailers as of November 2, 2026, with prices from €308 to €677, a €369 spread on the same certified stone. MOH London lists it at €677. 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.
