About this 3.91ct natural princess diamond

This 3.91ct natural princess sits in the three to five carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5191168393. Listed at 5 retailers as of October 31, 2026, with prices from €50,728 to €82,943, a €32,215 spread on the same certified stone. MOH London lists it at €82,943. 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.
