Vintage Silver and Horn Pendant Necklace

Interesting vintage horn, silver(tone?), and black cord necklace. The pendant is actually a bottle with a silver cap attached by a chain. I bought this new at Talbots in the 1980s and wore it with everything. It's still in very good condition. Time to pass it along. Laid flat, back neck to top of bottle is approx. 14.5". Bottle/pendant is approx. 2.25" from top of cap to base.
