My Crucifix Will Not Stay!

I recently purchased a Sterling Silver Crucifix from an antique shop near our home in Daytona Beach, Florida. I was replacing a gold Eagle pendant which was a gift from my father-in-law, after he died last year. I was a little uncomfortable wearing it, as I was never sure whether he liked me very much. We were on pretty good terms when he passed, but it was actually given to me by his surviving girlfriend, who was the trustee of his Estate/ I did wear it for over a year, but the wings had sharp edges, and cut into my neck at night, so I had been looking for a different pendant for some time. I actually was looking for a Wolf pendant, as my ancestors were German and Norwegean.

I happened upon the cross, in an Antique shop, in Deland Florida and bought it. After the first night, I awoke to find the cross on the floor next to my bed, right where I step when getting out of bed in the morning. I immediately reached for my neck chain, assuming it came loose during the night. It was still around my neck! I took a close look at the cross, thinking the little loop must have separated and slipped off the chain. But no, even though the loop is not soldered, it is a very strong little loop and the opening very tight, where it comes together. I could not force a tweet razor blade through the tiny opening! The chain is also relatively heavy, and the thickness of the thinnest place on the links is approximately 20 times thicker than the space in the loop.

I told my wife and son the story, so they examined it and declared it impossible to have come off the chain, without opening the clasp first! They offered all the possible scenarios, none of which happened. The chain and cross did not leave my neck all that day and night. So I put it back around my neck and the next morning, my wife asked if it came off again? I said no it did not.

But later today, I drove to the pharmacy to pick up my medicine, and as I was leaving and had just stepped through the automatic doors, then without explanation, I felt the Crucifix fall off the chain and down my chest! I grabbed my shirt and felt the cross and held it in place until I was able to get into my car and fish it out of my shirt. I examined the loop again and it was perfectly intact! I tried to pry it open with my fingers, with all my strength, but the gap did not widen at all. I just now was barely able to slide a thin piece of notebook paper through the space in the loop.

So my question is, Who is trying to tell me not to wear this Crucifix?
