An antique watch fob in the swivel style with reverse panels of Bloodstone and dark Carnelian, both of which are lovely specimens and could even be carved with a seal or crest to add a personal touch. This could be worn on a watch chain as originally styled or as a necklace for an individual look. With statement twisted chain details to the mount it is in slightly rosy hued 9ct gold with a full hallmark for Birmingham but the date letter is indistinct... however the maker's mark for William Oliver of Tenby Street in Birmingham used between 1886-1908 is clear to see.  

Measures an inch and a half lengthwise.
