This is a pendant necklace I've made from two round pendants I cut from a clear vodka bottle. They have been melted, annealed, and tumbled to a matte sea-glass finish. They are simply strung on a black waxed-cotton cord necklace.

Each pendant measures about 1-1/4 inches in diameter. The cord is 18 inches long, but please let us know if you'd like yours longer or shorter.
