About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1165235985. Listed at 19 retailers as of November 1, 2026, with prices from £6,950 to £12,485, a £5,535 spread on the same certified stone. NZ Jewellers lists it at £12,485. 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.
