12-Piece Fossilized Spiralite Quartz Shells For Sale

Discover a beautifully curated 12-piece lot of Fossilized Spiralite Quartz Shells, each showcasing stunning natural history and mineral artistry. These rare specimens originate from ancient marine environments dating back to the Cretaceous Period (100–50 million years ago), when much of present-day India was submerged beneath the prehistoric Tethys Ocean.

Formed from left-hand–coiled gastropods, these fossils have undergone a remarkable transformation over millions of years—now preserved as chalcedony quartz, often adorned internally with sparkling druzy quartz. Because these fossils are embedded deep within hard rock matrix, each piece is expertly hand-extracted, chiseled, and meticulously cleaned to reveal its elegant spiral structure.
