About this 2.06ct natural round diamond

This 2.06ct natural round sits in the two to three carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6551406667. Listed at 12 retailers as of November 4, 2026, with a 55% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
