I use high quality stampings to make my pieces. They are vintage and vintage tooled, dated from as early as 1880, and sourced from the USA and Europe. The base metal is brass. I have all my work electroplated here in Melbourne to a high industry standard.
The trimmings I used are all Swarovski Elements. Occasionally I may use another brand of supply, or a vintage supply, where it looks great and is appropriate to the design.
