This is a great pendant! It features a spotted orange stone with two eyes, in a modernist silver setting, unmarked but presumed to be sterling silver. The pendant is signed with a zigzag or conjoined MW hallmark. I have several pieces with this mark but have not been able to identify the artist. If you recognize the mark, please let me know. This pendant also has the number 70 on it indicating the year it was made - 1970. It hangs 2".
