The “Swimming Fish” Double Pendants are made from solid sterling silver. We have decided to keep them mis-matched (mixing the Carp (X’s), Salmon (scallops) and stripers) to add character. Please let us know in the notes at check-out if you would like a particular fish arrangement! The fish charm is 7/8” long and 3/8” wide, making the double Pendant about 1” long and 7/8” wide, and about 1.5” long with a stone. Genuine stones available are Silvalite, Aqua Blue Chalcedony, and Sapphire (navy). We also have aqua and periwinkle crystals in synthetic stones, and an option without stones.
