About this 1.51ct natural princess diamond

This 1.51ct 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 1427009335. Listed at 18 retailers as of November 5, 2026, with prices from $3,418 to $8,795, a $5,377 spread on the same certified stone. Adiamor lists it at $8,795. 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.
