About this 0.78ct natural princess diamond

This 0.78ct natural princess sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7566283802. Listed at 6 retailers as of October 31, 2026, with prices from €690 to €851, a €160 spread on the same certified stone. Blue Nile lists it at €851. 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.
