This necklace has a beautiful Priday Ranch Plume Agate that I've paired with a Pyritized Ammonite and accented with 18K gold balls.
The back of the pendant is cut open to show off the transparency of the center of the stone, as shown in one of the photos below. The entire necklace has been oxidized (blackened) to set off the texture and add interest.
The pendant hangs on an 17-3/4-inch custom chain. The back of the pendant has been textured and stamped with the hallmark and maker's mark.
Pendant measures 2-3/4-inches high by 1-1/8-inches wide.
