Mexican Vintage Filigree Bracelet

I acquired this bracelet from my aunt after she passed in the early 90's. After hours of on line searching I found that this bracelet is from Mexico and that the stone is a synthetic Lapis. My mother did tell me my aunt went to Mexico many years ago and she aged the piece to be about 60 years old. I took it to a jeweler and he said the marking says "Sterling Mexico". If anyone has any futher information I would appreciate it.
