About this 0.99ct natural princess diamond

This 0.99ct natural princess sits in the just-under-one-carat band, graded J 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 1232939166. Listed at 3 retailers as of October 29, 2026, with prices from £697 to £1,058, a £361 spread on the same certified stone. MOH London lists it at £1,058. 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.
