Swim with dolphins: sterling ring, abalone earrings + bonus charm/pendant

Great tribute to these gorgeous creatures. The sterling ring is size 8-1/4 and is marked Mexico and 925. The drop earrings are likely handmade and are slightly different from each other. They are unmarked. I'm including a dolphin charm or small pendant, which is unmarked but jeweller confirmed as silver. Everything is in very good condition, with some nice patina.
