About Plume Agate

Plume Agate: Life, Captured in Stone

Plume agate forms in ancient hot spring systems, shaped not just by geology but by life itself. These intricate formations are created with the help of thermophiles and extremophiles—heat-loving microbes that thrive in harsh, mineral-rich environments.

As these microorganisms go about their microscopic lives, they gather and deposit silica and other dissolved materials, slowly building delicate, feather-like plumes inside the stone. Each color and shape reflects a unique blend of clays, metals, and minerals, shaped by time, chemistry, and living systems.

What you're seeing inside plume agate isn't just a mineral pattern—it's a biosignature, a geological record of microbial life.

Famous deposits include Graveyard Point (OR/ID), Coyamito (MX), Marfa (TX), and our own Eastern Oregon finds like Widowmaker and Oregon Bumblebee.
