I've seen these labels in both red/gold and purple/gold. I think the starts are just decoration. Though I don't know by any means, judging by the shape and carving style and by the label style, I think these are Austrian and from the 1940s. I think the stem is amberoid/cultured amber (amber powder reconstituted with resin) as commonly used by Austrian maker Andreas Bauer which, along with importer Pioneer which sold Austrian meerschaums, also sometimes used these metallic labels and this sort of carving. It's almost certainly block meerschaum, and in this case I'm certain the stem is indeed amber. It's an elegant pipe and probably will smoke and color well.
