Massive 925 necklace

A substantial 925 necklace with a "sliding" light blue crystal (?) pendant. Marked with 925, see the last picture. The chain has a unisex design and looks great even without the pendant :) I can't say about the pendant's "eye," it could be topaz (real or almost real) or simply a pretty glass in an ornate silver frame. The total weight is about 14 grams. The total length is about 25 cm (*2). Vintage silver jewelry in good condition, with possible surface wear appropriate to its age. Shipping is not included and should be added according to the Andele price list.
