unknown markings on a ring

[babybearcolt]

I picked up this ring years ago and it has markings on it that I am not sure of. I know that 925 is silver, but there is is another marking which is 3 letters C A A. I am curious to know what it means and where the ring came from! Thanks

Hi! I am a new member of the forum, so I am curious about other members' silver mystery marks. A year ago, I happened to have a bracelet with the exact markings: C^A. I also researched and researched, but in vain. I know this answer is not of much help, but this IS a mystery mark!
Kind regards and good luck!
