About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6481481864. Listed at 21 retailers as of November 5, 2026, with a 192% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
