A Hybrid Goblet with 2 captive rings made from a piece of Horse Chestnut burl & epoxy resin coloured with mica powder.
Approximately, it stands 17.5cm tall, the cup diameter across the rim is 5.9cm and the base is 6cm.
 
You can see the original Wedding Goblet being made here on my YouTube channel:

The pieces I make are decorative/ornamental and are not waterproof or food safe.
 
DIsclaimer:
Wood is a natural product - I cannot guarantee that there won't be further movement over time or depending on the environment it is in, to me this can enhance the piece, but I understand not everybody will like this.
