Vintage gold blue topaz coastal beach hawaiian paperclip chain necklace choker

From my personal collection, a souvenir from my one and only Hawaii trip. A cute gold-plated, paperclip style chain with beachy charms (seashell, starfish, seahorse, sand dollar) and 5 various tear-drop shaped stones. I cannot say for certain what the stones are--open to suggestions. 12 grams total weight, 18" long. J79
