About this 1.29ct natural princess diamond

This 1.29ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555473176. Listed at 11 retailers as of November 6, 2026, with prices from £1,401 to £2,532, a £1,131 spread on the same certified stone. Helzberg Diamonds lists it at £2,532. 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.
