Vintage Sterling Silver and Semi Precious Stone Bracelet, Made in Mexi

This is a beautiful hand made vintage 1960s Mexican bracelet made of 925 sterling silver with semi precious stones of malachite, onyx, lapis lazuli and banded agate? I'm not sure of that. It measures 7" long laid out straight, is a little over 1/4" wide, and is in great used condition, ready to wear with the clasp in good working order.
