! Vintage Handmade Statement Necklace, Beaded with Celtic Pendant

Statement necklace! Multiple strands of tiny black beads with blue “surprise” accent beads. No fastener. It slips over your head. Total opening is about 23 inches. I do not know what this Celtic symbol/cross represents. Purchased new around 1999-2000. Gently worn a few times. Stored carefully ever since. Please see pics! Non-smoking / cat friendly home
