Doser: Mineralogy

Founder: Theresa Cowan

Rock(et) science: As a School of the Art Institute of Chicago senior, Cowan found inspiration in her requisite science class during a mineral classification lecture: Taken with the chemical composition and texture of the stones, she started experimenting with jewelry-making, and after graduating, launched an already booming accessories line.

Products: One of a kind, hand-crafted jewelry inspired by the earth. Cowan incorporates uncut and unpolished minerals into her rings, earrings, and necklaces to showcase their unique characteristics.

Why we love them: The lack of adornment–beyond functional wire-wrapping–highlights the naturally complex texture, form and color patterns of the minerals.

Dose appearances: June 5, July 10, August 14 and October 16.
