About this 0.31ct natural princess diamond

This 0.31ct natural princess sits in the sub-half-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 6561400609. Listed at 4 retailers as of November 1, 2026, with prices from $182 to $275, a $93 spread on the same certified stone. Rare Carat lists it at $275. 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.
