Gemstone Inlay Snuff Bottle Necklace
Snuff bottles were used by the Chinese during the Qing Dynasty to contain powdered tobacco. They were initially made for the emperor and the court, but eventually produced in much greater quantities for a public who enjoyed their functionality as well as their display as symbols of status.
In this day and age as a stoner, keep some kief or shake inside. Comes in handy when you think you're dry.
