Valdo Zeni's sterling silver pendants will come with the chain that we feel is best suited to their design. However they can be paired with two different types of 18" chain to create a complete necklace. Please email us at email@example.com if you'd like a different chain from what's displayed on the product image and we will do our best to help. Both chains can be used with most pendants however the spiga chain is a thicker weave and won't fit through every pendant that we have in stock. Some pendants are also made with their chain as an integral part of their design and can't be taken apart. If this is the case we will let you know.
