Sirena Carved Aventurine and Marine Shell Necklace

An exquisite exploration of maritime symbolism and structural geometry, the Sirena Necklace offers a masterfully balanced, one-of-a-kind statement. At the structural epicenter of this piece is a magnificent focal pendant bead, meticulously hand-carved from translucent green aventurine into the elegant, fluted contours of a sea shell.

Flowing outward from this carved centerpiece is a rhythmic sequence of soft mint aventurine spheres—each framed by detailed gold-plated bead caps—and alternating segments of delicate upcycled shell discs and pointed grey marine shells. To ensure an impeccable, organic drape, the necklace is expertly hand-knotted in deliberate segments. Measuring 16.5 inches with a 2-inch extension chain and a gold-plated lobster clasp, this limited slow-fashion creation brings an intentional, coastal luxury feel to modern dressing. While designed to stand alone as a solitary masterpiece, it shares an artistic lineage with the Sirena Tassel Earrings.

Artist’s Note

"With the Sirena necklace, I wanted the focal carved aventurine shell to feel like a modern, mineral relic found on the shore. To emphasize our commitment to slow fashion, I chose to pair these stones with pattern-banded, recycled natural shells. Beyond the architecture, I selected these materials for their historic symbolism: Aventurine is celebrated as a stone of prosperity, optimism, and heart-centered renewal. It is a completely unique, one-of-a-kind creation meant to bring a sense of grounded elegance to its wearer."
