The study of deep past often reveals hidden gems and magnificent treasures that can only be formed at geological timescales.

This bracelet features a large round bead of dinosaur bone. These hand-finished beads are agatized sauropod bone from the Morrison Formation of Utah. One of the most studied fossil beds of the upper Jurassic Period, the region was once home to a large floodplain ecosystem 150,000,000 years ago.

Over tens of millions of years, hard minerals, such as chalcedony and quartz, replaced the original organic material. The result is a beautiful marrow matrix exhibiting incredible detail and rich colors.

As pictured, the dinosaur bone beads on this bracelet are 12-13mm in diameter. This is larger than our typical bracelets so we've chosen to offset the beads with rugged, 10mm lava rock beads. The spacers on either side of the dinosaur bone bead are sterling silver.

Because this bracelet features larger beads we've made two different sizes: 7" (~17.5cm) and 8" (~20cm) circumference. The bracelets are constructed with sturdy but flexible black cord so they'll stretch a bit further.

The bracelet comes in a gray gift box with a small information card that provides background on the material and serves as the certificate of authenticity.

Please Note: As pictured, these beads vary widely in color and texture. Each one is absolutely unique and beautiful.
