Art Deco Rolled Gold Collar Necklace w/Peking Glass Stones

This is timeless with a very distinctive Art Deco flair that has come charging back to fashion now. This is an original: estimated to date to the 1930’s or 40’s. It is unmarked for metal content: it looks gold filled or maybe rolled gold at the lowest. It is signed with a maker’s mark though unfamiliar to me. 16 &1/4” wearable length 1/2” wide at the decorative central links 10.2 grams The triangular “lapis blue stones” are Czech glass known as Peking glass. It is in excellent condition overall. A light amount of wear to the back of the central links, otherwise perfect considering age.
