Lost high school class ring with blue stone and 'A.B.' initials in Corpus Christi during a beach clean-up.

I lost my high school class ring in or around Corpus Christi during a beach clean-up event last weekend. It has a blue stone with the initials 'A.B.' engraved inside. I’ve searched the area multiple times, but no luck finding it. It's very special to me as it has sentimental value.
