I also saw these in Seattle. They were in a boutique, one of three called Fancy, (Shmancy and Nancy).
Here's what the artist has to say:
"My current body of work combines my interest in plant life, jewelry, and sculpture.
The work consists of organic rings and necklaces that reflect an experimentation and exploration of materials, unique color combination, and texture. During the creation of each piece I focus on objects that are either found, bought, given to me, or created from other materials. I find it intriguing to use materials that have little monetary or social value in order to create something beautiful. It is important that each piece work as well off the body, as a sculptural work, as well as on.
I want the viewer to be able to adorn themselves with each piece and form a personal bond with my work. I believe that art that can be worn by the viewer creates more of an intimate bond between artist and wearer."
