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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567645709. Listed at 15 retailers as of October 31, 2026, with prices from £1,760 to £3,287, a £1,527 spread on the same certified stone. Helzberg Diamonds lists it at £3,287. 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.
