Materials and Process: All pieces are made by hand and worked using traditional hand engraving, and jewelry fabrication techniques. Materials include stainless steel bicycle spokes, bicycle chain links, and cogs. Most pieces incorporate semi-precious gemstones, many of which are sustainably mined in the USA, and some of which I form and polish by hand. All sterling silver comes from Harmony Metals and is 100% recycled. I use custom alloyed 22k and 18k gold.
