Our collection of classic bands for men and women are crafted, cast and finished by hand in our San Francisco studio and stamped with the Bear Flag symbol.

River Gold Studs

These one of kind single gold nugget stud earrings were panned for on the North Fork of the American River in California gold country. Each piece shows it's unique alluvial history with individual river worn shapes. Sold Individually.

San Francisco Made

Made to order in our San Francisco Studio and based on tried-and-tested styles that maximize comfort and wearability, and showcase the properties of this unique and beautiful material.

24k Gold

24k River Gold is not mixed or alloyed with other metals and has its own unique and vibrant color. This also means it will patina more quickly than lower karat gold because it's softer, yielding a texture and look that is completely unique to its wearer. We think of it as imperfectly perfect. 

Will it scratch or dent? Absolutely. Like your favorite pair of jeans, your band will become imprinted with your life experiences and adventures, and become more beautiful with age.
