About this 0.83ct natural round diamond

This 0.83ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2507386502. Listed at 9 retailers as of November 2, 2026, with a 54% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
