You can make or buy tagua nut rings – a great use for smaller tagua nuts. Drilling through the center also eliminates the void but be careful when you drill: you will need a very sharp drill, preferably a drill press, and a vice. Drill s-l-o-w-l-y – you don’t want to crack it! After it’s been drilled, you can carve it, sand it dye it and polish it to make a beatiful ring! Great as an insert into a traditional metal ring as well, either dyed or scrimshawed.
