About this 0.81ct natural princess diamond

This 0.81ct natural princess sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5242121529. Listed at 2 retailers as of November 1, 2026, with prices from £607 to £870, a £263 spread on the same certified stone. 77 Diamonds lists it at £870. 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.
