Genuine sea glass and sea shells found at the beach by me, Julia, the artist here at Earth Eye Jewelry. I make sure each piece is made with unmatched craftsmanship, and authentic materials. All pearls and crystals that may be included in my pieces, along with the sea glass and sea shells, are all real offerings from the Earth. I use comfortable, durable string that is hand-twisted and hand-knotted by me. You're welcome to wear your Earth Eye pieces in the water, these pieces are made to last.
