My wooden deck’s beams are about 3/8" apart and my wedding ring fell right between the beams!

Luckily about 6" down the roof of the unit below us begins (so i can see the ring if i look between the beams).

Unfortunately I don’t know what tool i can use to grab it (I have one of those tools that pick up screws, but the width is too big…. i am going to try to purchase a smaller one today).

The ring is titanium…… any suggestions?
