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 VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 691554183. Listed at 17 retailers as of November 4, 2026, with a 103% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
