Black Water Siren Studio creates finely handcrafted art jewelry expressing ancient and modern symbolism in gem-embellished sterling silver, copper, bronze, and 14k gold. Cyndia's jewelry is collected on four continents by enthusiastic and loyal customers. In business since 1989, Black Water Siren jewelry can be found in select boutiques throughout the United States, Canada, and the United Kingdom, and in 2008 was featured in Femail Creations, a national gift catalog showcasing female designers. In 2015 the Erzulie Freda vodou veve pendant was featured on the CBS television show "NCIS: New Orleans". Several celebrities also own Cyndia’s jewelry.

Black Water Siren Studio is located just ten miles east of the Sapphire Mountains and thirty miles south of the Garnet range in Montana, the Treasure State.

Each piece of Black Water Siren jewelry is individually handcrafted by Cyndia in her studio. Cyndia uses labor-intensive techniques such as hard-soldering, stone-setting, lost wax casting, hand forging, metal chasing, and surface finishing to achieve each piece’s unique and original look. Carefully selected gems, often chosen for their rarity or unusual quality, are meticulously added to give vibrant color, sparkle, and individuality to each creation. Most of Cyndia’s designs are one of a kind or very limited production to ensure that no two pieces are exactly the same.

Cyndia Reddish is a self-taught metalsmith and jewelry artist. Jewelry has been a life long passion for Cyndia; her earliest memories are of a large box of her mother's costume jewelry, which she would spend hours taking apart and redesigning as a young child. Cyndia has been creating original art jewelry ever since, drawing inspiration from her environment, personal experience, and intuitive talent.
