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 5242118994. Listed at 8 retailers as of November 4, 2026, with prices from $2,431 to $4,056, a $1,625 spread on the same certified stone. Wholesale Diamonds Direct lists it at $4,056. 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.
