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 2, 2026, with prices from $5,439 to $10,430, a $4,991 spread on the same certified stone. NZ Jewellers lists it at $10,430. 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.
