About this 1.28ct natural princess diamond

This 1.28ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 274733835. Listed at 3 retailers as of November 1, 2026, with prices from £669 to £1,031, a £362 spread on the same certified stone. Yorxs lists it at £1,031. 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.
