You are buying an original design by the original artist. I hand assemble my jewelry at my home studio, including all wire wrapping, soldering, hand fabrication, etc. I make and sculpt many items myself (I do not use mass produced findings). When needed, I work with a few reputable foundries that I have good long-standing relationships with for casting. The silver that I use is the highest quality .925 sterling silver which is nickel free. I also make my jewelry out of pure silver clay.
