About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two 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 1563646503. Listed at 11 retailers as of November 4, 2026, with prices from $2,894 to $6,008, a $3,114 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,008. 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.
