Avalon Priestess Vintage Renaissance Necklace, 1 of a kind! Never Worn!

This stately King Arthur Era necklace brings to mind many Girlhood dreams of being a High Priestess of Avalon! I imagined myself wearing just this style of unique and crafted jewelry when my Prince came to call!...So when I found it...I had to have it! (yes, I found the prince too!)....and yet, I have never worn this piece. In Spring 2002 in Austin TX , as I strolled down Congress Avenues quirky and weird shops of awesomeness! I spied this mesmerizing beauty, so I bought it! But have never ever worn it.....Sad? very! BUT YOU CAN! To be honest, I'm no natural stone expert and am not 100% sure if this Natural Stone necklace is adventurine, green turquoise, or what.....it is a lovely green with natural veining throughout I do know it is unique and at least the only one like it I have ever seen. I'm sure It's handmade...I remember the seller telling me that... please feel free to ask any questions, Offer any knowledge you may have about this piece or make an offer......thanks
