Handmade sterling chain: just over 1/2" wide X 18 1/2" interior; articulated sterling center piece: 3 1/2" X 1 1/2"; Sterling pendant: including J hook: 3" X 1 5/8"; White Oval insert: vintage 40mm X 30mm layered "pate de verre" like milk glass with "M" like design. This is the only chain that I hand forged myself, as it is a very labor intensive process, especially with heavy 14 gauge precious metal. At the moment my poor aching hands are painting oils...maybe more metalwork later...
