Apparently, this thimble must have been purchased as an easy to travel with souvenir from a trip to Germany. Henckel's is a well-known manufacturer and retailer of fine wares.
The interior of the thimble and the bottom below the enamel work are gold-washed. It has a blue stone dimpled top.
Excellent condition. Rare color.
Please note that the last two pictures show the thimble after being polished. Also the hallmarks are on the knurled part of the silver and we were unable to get a clear photo, but they are there.
