About this 0.77ct natural round diamond

This 0.77ct natural round sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 5553616729. Listed at 24 retailers as of October 28, 2026, with a 189% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
