Antique 25" Victorian Opal Sliding Pendant on a Gold-Filled Guard Chain Necklace

This is a beautiful Victorian era tiny slide pendant with 5 little opals and 1 missing opal on a guard chain necklace. The pendant and chain are both gold-filled, and there are areas where the gold has worn away. The clasp is stamped 1/10 and S&Co. Overall, the piece is still in very great shape. The chain is approximately 25in long. *The opals have not been professionally tested to confirm if they are real or not.
