This amazing Dendrite Opal cabochon is set in a fine silver bezel and suspended with Argentium Sterling Silver from a Sterling Silver 'branch'.  Each of these stones is completely unique.  The detailed patterns are formed by iron, manganese or other metalic oxides and resemble ferns, trees and mosses.  The opal measures 3.5cm x 1.8cm and is on an 16" sterling silver chain and finished off with a 2" extension chain
