vintage black and white rhinestone bracelet (Old Hollywood Glamour, but Goth!)

This gorgeous sparkling black rhinestone bracelet with tiny white rhinestone accents belonged to a friend of my grandmother's who had a fantastic midcentury costume jewelry collection (she was a former model.) I'd guess this piece was from the late 1950s - early 1960s based on the rest of her collection, but I cannot be sure. (If you know more about it, please leave me a comment or send a message!) I love its luxe Old Hollywood glamor girl feel, and its black (but still sparkly) color palette! Please examine photos carefully for condition; some of the tiny rhinestones are gone, and a few links are no longer attached. (Price reflects these flaws.) Clasp seems functional, and I think the minor damage makes this a very wearable vintage piece, rather than one to lock up tight as a precious collectible. (As you can see from the overall bracelet photo, no one will notice anything's missing when it's worn!) I cannot see any maker's mark or metal stamp. Bracelet is just over 7.5 inches long, as shown. Please see my closet for other fantastic vintage jewelry pieces from this collection!
