∆ Onyx - 6 sided
∆ 20 inch thick stainless steel  chain with snake head detail
∆ This chain is prone to kinks, I make sure there is no kinks on it before sending it out but shipping may cause it to kink again, I find that a circular motion usually resolves it. 
 
The noble Onyx is a most ancient stone, known and utilized by even the earliest civilizations for its powerful energy and somber beauty.
