9ct GOLD LANTERN PENDANT on Unusual 30 inch 9ct Gold Chain 17.48 grams

9ct LANTERN PENDANT & 30 INCH CHAIN. The detailed lantern pendant has a hinged opening door that clicks shut and bevelled window sections. He faceted top and the connector ring appear to be white gold. Given to me in the 1970's I was told it was a one-off. The very unusual chain with long twisted links is marked 375 by the bolt ring.

Total weight 17.48 grams.
