Flower necklace (shorter style good for layering)

Lovely little necklace I’ve owned for years and have worn. I like it layered with multiple necklaces. Take a peek at the pictures and look how beautiful the chain is in detail. There is also a stamp I tried to magnify but I still have no idea what it says. Chain necklace and base of pendant are like a dark charcoal silver. Measures approx 16”
