Corrected entry: After Samantha and Richard go 'skinny dipping', they start dancing in robes by the pool. Samantha is still wearing what look like expensive dangling diamond earrings, and has obviously just swam in chlorinated water with them on. Samantha is known for her expensive taste in clothing and accessories; so even if her earrings are not actual diamonds, they are probably still very expensive, good quality jewelry. It seems illogical that she would risk damaging expensive earrings, wearing them while swimming. Even if she forgot to take them off before getting in the pool; they are very long dangling earrings, and she would have certainly noticed pretty quickly that she had them on.
