About this 0.91ct natural princess diamond

This 0.91ct natural princess sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556223834. Listed at 4 retailers as of November 4, 2026, with prices from $887 to $1,124, a $237 spread on the same certified stone. Blue Nile lists it at $1,124. 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.
