This rare early Victorian muff / guard chain is made from plaited human hair,the strands are held in place with 9 carat gold bands,the slide in clasp works well,the outer case of the clasp has a sleeve of 9 carat gold over a steel liner,I guess this is for strength.None of the gold is marked however I have acid and electronically tested it,the test results were 9 carat gold.The total length is 54&1/2 inches)138.5cm).If you have any questions please message me,it will be a pleasure to assist you.
