Natural Opalized Clam Shell — Authentic Fossil Specimen
Millions of years ago, a clam shell was slowly replaced by silica — molecule by molecule — until it became something extraordinary: a fossil that glows with the subtle play-of-color found only in natural opal. These opalized clam shells from Idaho are among the rarest intersections of paleontology and gemology, prized by fossil collectors and mineral enthusiasts alike.
Each purchase includes one specimen, hand-selected from the six pictured examples. If you have a preference for a specific piece, contact us before ordering.
