About this 6.5ct natural cushion diamond

This 6.5ct natural cushion sits in the over five carat band, graded G 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 2221177458. Listed at 13 retailers as of October 31, 2026, with prices from €142,211 to €246,778, a €104,567 spread on the same certified stone. MOH London lists it at €246,778. 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.
