Silver pyramid necklace small delicate

This necklace is silver with a pyramid at the end attached to the necklace. Not a medallion style that moves around but this piece is made to stay as intended. With the style of this necklace, without verification, it's very elegant and could be actual stones inside. However, I'm selling as silver costume jewelry price as I've no authentication. 1 cm pyramid. 22 cm tip to tip as shown in photos.
