About this 2.5ct natural round diamond

This 2.5ct natural round sits in the two to three carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 7418257843. Listed at 11 retailers as of November 4, 2026, with a 25% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
