About this 1.55ct natural princess diamond

This 1.55ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6421251715. Listed at 21 retailers as of October 31, 2026, with prices from $6,250 to $16,223, a $9,973 spread on the same certified stone. Adiamor lists it at $16,223. 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.
