C-clef instrument players are often overlooked when it comes to designing music-themed accessories. Just as a quartet is incomplete without a viola, our product line was missing a C-clef piece! So, we had a lovely artistic rendition of the clef in front of old music sealed behind a 1" square of glass. The bail is silver-plated and the back is sealed with a water resistant jewelry-grade resin (although just to be safe, don't wear it swimming or in the shower). The bail is silver-plated and the pendant is hung on your choice of an 18" black cord, silver twist chain, or silver link chain.
