Silver bracelet lost on Dunfanaghy beach

A silver chain with the Celtic circle on it. The chain may be broken. Has huge sentimental value to me as I got it from my boyfriend and hadn't taken it off since. I lost it when I was on Dunfanaghy beach last Tuesday, near the second ringbuoy when you go to the left from the entrance. It would mean the absolute world to me if I could find it.
