About this 1.55ct natural princess diamond

This 1.55ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566121716. Listed at 8 retailers as of November 6, 2026, with prices from $3,767 to $5,173, a $1,406 spread on the same certified stone. GemTrove lists it at $5,173. 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.
