About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565009419. Listed at 16 retailers as of November 5, 2026, with prices from $3,370 to $7,778, a $4,408 spread on the same certified stone. NZ Jewellers lists it at $7,778. 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.
