Sterling Silver, White Topaz, and White Freshwater Cultured Pearl (14.5-15 mm) Drop Earrings An inverted sterling silver and white topaz teardrop supports a freshwater pearl, whose impressive size and lustrous surface make each of these drop earrings a true showstopper. The natural properties and process of pearl formation define the unique beauty of each pearl. The image may show slight differences in texture, color, size, and shape. Carved rings are naturally occurring imperfections that result from the pearl rotating inside the mollusk as it is growing. They define the unique beauty of each pearl and may vary in size, number and depth per pearl.
