About this 5.45ct natural cushion diamond

This 5.45ct 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 2231071182. Listed at 7 retailers as of October 31, 2026, with prices from €124,300 to €192,351, a €68,050 spread on the same certified stone. MOH London lists it at €192,351. 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.
