Rare Black Ammonite Statement Cuff and Ring Set for Women

From the private Kat Kouture vault comes this rare, one-of-a-kind black ammonite cuff and statement ring set—a dramatic pairing of ancient fossil, sculptural metalwork, and unexpected rhinestone glamour.

Both pieces feature substantial polished ammonite fossils in deep black, charcoal, brown, and muted gold tones. Their natural spiral chambers and organic markings preserve millions of years of geological history, while sweeping rows of clear rhinestones introduce a flash of unapologetic decadence.

The cuff centers on a commanding black ammonite mounted across a wide gold-tone metal band. Dark metallic chain fringe spills from beneath the fossil, adding movement, texture, and a slightly dangerous edge.

The coordinating oversized ring features a second ammonite fossil embellished with curving rhinestone lines and an angular silver-tone sculptural accent. Monumental in scale and entirely unconventional, it is closer to a miniature art object than a traditional ring.

Together, the pieces create a striking tension between the primordial and the glamorous—ancient fossils transformed into high-art adornment. They may be worn as a coordinated set or separately when one extraordinary statement is sufficient.
