About this 13.18ct natural marquise diamond

This 13.18ct natural marquise sits in the over five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2233957923. Listed at 3 retailers as of October 31, 2026, with prices from €553,044 to €681,357, a €128,313 spread on the same certified stone. Yorxs lists it at €681,357. 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.
