From the "Deep Sea Luxe" jewelry collection: Fabulous seashell fossils dangle beneath a gorgeous boulder opal (featuring shades of deep blue and purple), a rose cut freeform tanzanite, three sapphire briolettes and a teeny Australian opal bead. This pendant is strung on a deep blue/purple leather cord with handmade sterling silver "M&M" end tabs. FYI: These glittering seashells were excavated from the Sahara desert. A gazillion years ago, it was a sea floor.
