Purchased this awesome pendant at a festival in California in the early 2000. This a festival piece created by an artist. Crushed Turquoise has been carefully mixed with a Phosphorescent Powder, then inlaid into the center of this unique pendant -- causing it to gently "Glow" in the dark, in addition to its vibrant color during the day! Still glows when exposed to light before darkness. 2” large pendants with gold bale. Very unique and individual pattern to each pinecone piece. This one is extraordinary.
