About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 6441911939. Listed at 8 retailers as of November 1, 2026, with a 37% 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.
