About this 3ct natural round diamond

This 3ct natural round sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by GIA 2231289257. Listed at 16 retailers as of October 30, 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.
