About this 3.01ct natural round diamond

This 3.01ct natural round sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2554414581. Listed at 18 retailers as of October 30, 2026, with a 35% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
