Everything from the top to the bottom of these little jellyfish is handcrafted. The main body of the jellyfish is a 9mm turquoise. The hood of the jellyfish is hand-forged from sheet metal using a variety of tools to give it dimension. The tentacles are also hand-forged and hand-shaped to give each one a unique character. Even the 20 gauge ball pin earwires are hand-formed by me to ensure quality and consistency. Then these little guys are put through a special strengthening process to make sure they will stand up to the test of time. These jellyfish are made of .925 sterling silver. They measure approximately 1.75" (4.445cm) long and each one weighs about 3.06 grams.
