It features the Virgin Mary above the water with a scuba diver down below. Nicely detailed and measures a bit larger than a U.S. Quarter. Has some weight to it at about 6 grams. The reverse side of the medal reads, " In Case of Accident Call A Priest". Chain shown is for demonstration only. It does not come with one. I have 5 of these available, buy a matching one for a friend! Very nice piece!
