About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded G 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 2567401676. Listed at 13 retailers as of November 5, 2026, with prices from £1,428 to £2,583, a £1,154 spread on the same certified stone. Helzberg Diamonds lists it at £2,583. 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.
