About this 1.7ct natural princess diamond

This 1.7ct 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 6565282208. Listed at 6 retailers as of October 29, 2026, with prices from $5,515 to $6,844, a $1,329 spread on the same certified stone. Blue Nile lists it at $6,844. 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.
