About this 1ct natural princess diamond

This 1ct natural princess sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2554401592. Listed at 23 retailers as of November 5, 2026, with prices from $1,405 to $4,385, a $2,980 spread on the same certified stone. NZ Jewellers lists it at $4,385. 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.
