About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of November 4, 2026, with prices from £811 to £954, a £143 spread on the same certified stone. B2C Jewels lists it at £954. 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.
