About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6243120612. Listed at 10 retailers as of November 6, 2026, with prices from £1,557 to £2,866, a £1,309 spread on the same certified stone. Helzberg Diamonds lists it at £2,866. 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.
