If you are looking for a truly unique ring, you should pay attention to this cool Kickstarter projet by Enchanted Soul. The project owner can already rejoice, because its Kickstarter was funding within two days, and still progressing.
The project started out of frustration when purchasing a wooden ring that wasn’t as good as advertised online. Challenge was taken to create a better quality ring, which was achieved very well. You can see the results on the Kickstarter page here.
