About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 510194238. Listed at 16 retailers as of November 4, 2026, with prices from $9,811 to $18,815, a $9,003 spread on the same certified stone. NZ Jewellers lists it at $18,815. 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.
