About this 3.17ct natural round diamond

This 3.17ct natural round sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6233983322. Listed at 19 retailers as of October 27, 2026, with a 28% 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.
