Four wood triangles are connected by brass rings to create a little armored plate. Wood is dyed ash, and was manufactured in the 1970’s, possibly to be incorporated into some type of macramé craft. The brass chain and screw-type closure were also made in the 70’s. We've protected the wood with food-grade mineral oil, but to prolong the life of this piece, please don't wear it in the shower. The total necklace length is 20”, so the 1.5" wide kinetic wood feature sits right in the middle of the breastbone.
