Vintage silver bracelet composed of three interlocking wavy bangles

This vintage bangle consisting of three wavy interlocking bangles is stamped MEXICO 925. Unfortunately, I cannot identify a brand . I thought it belonged to a seer as shown in the last picture with a pair of Monies earrings but I cannot find a brand marking on the bangles . Each bangle measures approximately 2.5" diameter and the rich patina gleams different colors depending on lighting . Some scratches as shown but very good vintage condition . Believe to be early Y2K
