About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558596743. Listed at 3 retailers as of November 2, 2026, with prices from £1,862 to £3,015, a £1,154 spread on the same certified stone. MOH London lists it at £3,015. 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.
