From the latin word for “leaf”, Folium is shaped by nature’s quiet intelligence. A fine jewelry studio rooted in craftsmanship and time-honored techniques, each piece is designed as a modern heirloom…made to be worn, lived with and passed on.

All Folium jewels are made by hand in our workshop in California, using traditional techniques. Each ring is shaped, engraved and finished individually, honoring the marks of the maker rather than erasing them.

Yes. Each piece is handcrafted from start to finish. Subtle variations are signatures of the hand, evidence that no two pieces are ever exactly alike.

Folium works exclusively with precious metals, specifically 18k yellow and white gold, as well as platinum, and carefully selected gemstones. Materials are chosen for their beauty, durability, and longevity, designed to age with grace over decades, not seasons.

Custom work is a pillar of Folium. We welcome personal symbols, engravings, and bespoke adaptations of our designs. Custom commissions are handled on a limited basis to ensure thoughtful collaboration and craftsmanship. Contact directly to discuss your vision.

Because each piece is made by hand, production times vary. In-stock designs typically ship within 2 weeks, and wholesale store orders in 4-6 weeks. Custom and engraved pieces require additional time, usually around 8-12 weeks. We believe patience is part of the value of the object.

Folium ships to the USA and Canada. Shipping times and duties vary by destination and are the responsibility of the recipient. All shipments are securely packaged and fully insured.

Folium jewelry is made to be worn, but we recommend removing pieces during heavy activity or chemical exposure. Over time, precious metals can develop a natural patina; many collectors consider this part of the piece’s story.

Due to the handcrafted and often personalized nature of our work, most pieces are final sale. If you have concerns about fit or details, we encourage reaching out before placing your order and we’re happy to guide you.

Some designs return, others do not. Folium jewels are produced in limited quantities. We recommend joining our mailing list for early access and updates on new releases.
