This Sterling Silver Butterfly Pendant was Hand Cut from a Butterfly Coin that was minted on the Island of Mauritius in the Indian Ocean. The Coin was minted only in 1975 and was a Collectors issue Coin, never being used in circulation. The Butterfly used on the Coin is a Blue Swallowtail sitting on three Flowers. It has been a great seller for us in the Two Tone version we do and looks great in Sterling Silver as well. The Pendant comes with a Sterling Silver Snake Chain available in four different lengths.
