Cubes of Slate with Pyrite Necklace and a Murano-Style Glass Pendant/Clasp17" slate necklace with pyrite infused into the slate. 1" Murano style glass pendant on the necklace with a unique European attachment system in which the pendant is also the clasp. Pushing in on the spring loaded pendant ends allows the pendant, with a quarter twist, to be completely removed from the necklace. One can then change out the pendant for a entirely different style pendant. Very unique, versatile and innovative. 18" overall necklace length
