About this 0.91ct natural princess diamond

This 0.91ct 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 1558302571. Listed at 7 retailers as of October 31, 2026, with prices from £647 to £1,129, a £482 spread on the same certified stone. GemTrove lists it at £1,129. 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.
