About this 0.64ct natural princess diamond

This 0.64ct natural princess sits in the half to three-quarter 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 5566219772. Listed at 5 retailers as of October 31, 2026, with prices from £420 to £531, a £111 spread on the same certified stone. Blue Nile lists it at £531. 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.
