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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567428497. Listed at 5 retailers as of October 29, 2026, with prices from £608 to £748, a £140 spread on the same certified stone. Blue Nile lists it at £748. 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.
