Simply Charming Necklaces are on nickel free chain. The length of the chain is 24 inches. Message me if you want it shorter.
Most metal spacers, bead caps and charms are also nickel free. Beads on my jewelry are made of a variety of material, stone, glass, Chinese crystals, cracked glass, agates, glass pearls, seed beads, metal wood, polymer clay, acrylic or any beading material I think looks interesting.
