Vintage Germany Shimmer Light Gold 4 Strand Necklace

Vintage Germany Shimmer Light Gold Tone 4 Strand 17" Necklace. Each strand has a different chain link design, pull tab hook closure. I do not know what the metal is but it shimmers at every angle and has no tarnish and very lightweight. The Stamp marked "Germany" indicates it has been manufactured pre world war 11 or post 1990, my guess is post 1990. It is in excellent preloved condition.
