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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555421624. Listed at 5 retailers as of November 4, 2026, with prices from £415 to £820, a £404 spread on the same certified stone. GemTrove lists it at £820. 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.
