About this 5.18ct natural cushion diamond

This 5.18ct 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 2233840053. Listed at 5 retailers as of October 31, 2026, with prices from €83,746 to €112,913, a €29,167 spread on the same certified stone. Yorxs lists it at €112,913. 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.
