Glass opal cabochon pendant green and blue. Victorian Style necklace

The cabochon changes color as the light shifts. Alternately green, blue and gold, the blue color glows above the top of the pendant as it moves. Set in a vertigris copper bezel accented with side charms, the necklace is finished with mottled aqua Czech glass beads and copper toned filigree and a delicate copper chain and toggle. Measures 10" from toggle to bottom of bezel. Vintage style.
