About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by HRD 260000059811. Listed at 13 retailers as of October 29, 2026, with a 74% 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.
