About this 0.77ct natural princess diamond

This 0.77ct natural princess sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565317876. Listed at 6 retailers as of October 31, 2026, with prices from $818 to $1,008, a $190 spread on the same certified stone. Blue Nile lists it at $1,008. 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.
