Beautiful French Art Glass slide for a ribbon choker. Hallmarked for France with another mark I can't quite make out, the glass design of these deco flowers in opaline is a design signature to Lalique pieces. It should look lovely on as it has a wide slide and loops at the top to sew it to the ribbon so it won't fall forward. Dating from the early 20th c.
