I purchased an old Chinese bamboo and bone MahJongg set after learning how to play in 2023. Then I had to figure out how to make jewelry pieces from the tiles. So far I have only made one piece medallions backed by sterling silver with the tiles.
The "Chinese money" or counters is more interesting. I coated the bone with colorful epoxy resin. Then I sand it off, drill holes and make 3 piece earrings with a sterling silver post.
