Engagement ring found and returned from private beach in Eastham Massachusetts

Erika and her family were visiting the cape from Canada, they were staying a very short walk from a private beach in Eastham. While sitting in her beach chair in the water her ring came off her finger and buried in the sand in about 1ft of water . I received a text from her around 1030pm on aug 26 but my phone was in my truck, Monday morning came around and I responded to her when I got to work and we made arrangements to meet after I got out of work. I got to the house they were staying at around 6pm we walked to the beach and about 10 minutes later the ring was back on her finger
