Tandem Co.

Tandem Co., founded by Hannah Gross and Arya Acacia, is a metalsmithing studio based in Bozeman, Montana. Both earned their BFA from Montana State University in 2026, where their individual practices evolved into a shared way of seeing and making.

Hannah’s upbringing in Colorado’s Front Range and Arya’s in Minnesota’s industrial landscape inform their perspectives, which came together through a natural alignment of process and intention. Their partnership is rooted in trust, curiosity, and a mutual commitment to creating with care.

Working in recycled sterling silver and ethically sourced stones, each piece is fabricated entirely by hand, from melting and rolling silver to fabrication, casting, stone setting, and enameling. Their work reflects a deep respect for material and traditional metalsmithing techniques.

Their jewelry encourages individuality through subtle detail, offering intentional adornment designed for everyday wear and lasting connection.
