Roberta Weisenburg


Roberta Ann Weisenburg started her jewelry career as an apprentice to a goldsmith in 1981. She moved to San Francisco in 1984 and set up a studio that she maintained for over 28 years. She attended schools including GIA International, the Revere Academy of Jewelry Arts, City College of San Francisco, Jewelry Studies International, The Enamel Society of Northern California and various workshops given through the Metal Arts Guild of the Bay Area.  In 1999, Roberta's life changed through learning the ancient craft of granulation - she fell in love with this technique and her 22k gold granulation work has been featured in the Lark book publication '500 Earrings'. In 2012 Roberta became an Argentium Certified Instructor of Argentium fusing techniques. She currently teaches classes for adults and high school students at the Hui No'eau Visual Arts Center in Makawao, Hawaii and also teaches privately. Roberta is continually inspired by the beauty of her surroundings and is grateful for being able to give back to the community through teaching.  You can see her work in local exhibitions and galleries.

Jenny Reeves


Jenny Reeves designs jewelry with three things in mind - artistry, craftsmanship, and wearability. Her signature line fuses ancient techniques with modern designs, resulting in richly textured pieces with clean lines and classical proportions. A Philadelphia native, Jenny had many jobs - lifeguard, accountant, muralist, bartender - before discovering a passion for metalsmithing. Whether a bold statement piece or a contemporary classic, each is crafted to highlight the balance of opposites and interplay of surface, line, and form. The result is unique jewelry with exceptional wearability. Jenny’s work is regularly featured in jewelry publications including MJSA Journal, Lapidary Journal Jewelry Artist, In Store Magazine, Metalsmith Magazine, and National Jeweler. She is a graduate of the Revere Academy of Jewelry Arts where she teaches several classes and is a member of the Contemporary Jewelry Design Group, the Bay Area Metal Arts Guild and the Argentium Guild. 

Vickie Hallmark


Vickie Hallmark draws inspiration for her jewelry from the fauna and flora that gather around the stock tank pond in her central Texas garden. The scenes that appear in her work are based on studio views of the treetops, where warblers and wrens flit from branch to branch, or adapted from close examination of the native plants she cultivates. Each bird, leaf and flower is hand-sculpted in silver or gold clay with the individuality that nature imparts, with details interpreted through an artistic eye. Once reduced to pure metal, these tiny elements are then combined with Argentium Sterling Silver, high karat gold and colorful gemstones to create charmingly individual vignettes meant to be worn and treasured. Trained as a research scientist, Vickie studied gold and silver in the laboratory for many years before returning to her birth name's heritage of metalsmithing (a hallmark is a maker and purity mark for fine metals). She sought training from recognized master jewelers to learn the craft, but combined the techniques they taught with her own experimental and artistic nature to develop a unique combination of high tech materials and processes. 

Annette Petch


My designs are based on natural forms including leaves, flowers, buds, seed pods, and shells, and the secret spaces found within them. I like to incorporate texture, and the sounds of pebbles on the beach, wind rustling through the leaves, or water running over stones. In 2013 I was very fortunate to be awarded some funding by Arts Council England, which enabled me to do some research and develop new work in Argentium silver. This has enabled me to spend time experimenting with Argentium, and I have developed a new range of pieces, the Frond collection, which exploit the wonderful malleability and ductility of this metal. I am writing a blog to record some of my Argentium adventures, you can read it here. I showcased my new pieces in my solo exhibition ‘Immaculate’ at Ruskin Arts and Crafts during the Galvanize Festival. I sell my work through exhibitions and galleries, and undertake private commissions. Annette runs Argentium classes in her studio in Sheffield, England.

Christine Zock


It's a pleasure for me to create clean jewelry designs for everyday use. I enjoy using high quality materials such as gold and Argentium Silver, they are wonderful materials to work with, and they compliment and support the beauty of my designs.


I have a classical education as a goldsmith. During my early years of training, I worked in goldsmith workshops in North Germany and was always very fortunate to learn so much from highly talented goldsmiths.


I took a big step across the Atlantic to San Francisco, where I had a studio in Noe Valley. Back in Germany I opened my own studio near Munich and this is where I also give Argentium classes.

2018, I passed the 'Argentium Instructor' examination. I enjoy teaching and introducing people the magic of Argentium in German and English.
