About this 1.28ct natural princess diamond

This 1.28ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5212625488. Listed at 10 retailers as of November 4, 2026, with prices from $1,739 to $3,769, a $2,030 spread on the same certified stone. MOH London lists it at $3,769. 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.
