I came across an old ring in my mother’s jewelry and the markings on the back have me stumped
The ring is primarily silver with gold on the top.
One of the three marks on the back of the ring is "10K", which I take to refer to the gold portion of the ring.
The second mark is a series of letters/numbers. They are blurred with age but I believe that they are "C" "N" "U" "T" "Y" "9" "2" "5". I believe that the '925' indicates that this is sterling silver, but the letters area a mystery to me.
The third mark is a cross with arms of equal length and flared tips (like a Templar Cross). I thought that this would be an easy mark to identify, but after a couple days research I realize that I was wrong in this assumption.

Any suggestions as to where I should look for more info on these marks would be greatly appreciated.
