This was an early a foray into more substantial pieces of woven wire jewelry. I named this pendant "Maelstrom". The opal in the center is meant to represent calm in the midst of a swirling tide. This particular opal was supposedly mined in Australia, if I understood the seller correctly (he was 96 and kind of hard to understand). The weave wire is fine silver. The base wire is argentium. There is a sterling silver frame for stability. The chain is made from argentium. The lobster clasp and the clasp rings are silver plated base metal. The beads are opalite and silver plated copper. For what it's worth, my original intention was to lightly patina the silver beads, but a few kind of got away from me, and I liked the look, so I went with it.
