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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1565759798. Listed at 11 retailers as of November 4, 2026, with prices from $3,209 to $5,800, a $2,591 spread on the same certified stone. Helzberg Diamonds lists it at $5,800. 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.
