The short answer is no. Not really. At least not the way I used to make them.

When I first started making rings, I was a high schooler without access to tungsten cores. I did not have crushed stone or opals or any of the materials I work with now, just wood and nothing else. I would take three or four pieces, glue them together, clamp them, and wait. Once they were dry, I would drill a hole through the center with my high school's drill press, then take that block to the lathe and try my best to shape it into something round that could fit on a finger.

That did not go well most of the time.

The rings would end up uneven, thickness would vary significantly from one side to the other, I even burnt the inside of one ring so badly from friction on the lathe that it looked charred. Some of them just broke in half for no reason I could figure out and I sealed them with oil because that is what people said to do, but oil does not hold up, it wears off and does not protect much of anything.

CA glue would have been better, I know that now, but even if I had used CA back then, it would have been a thin layer on the surface. Thin layers wear down fast when you wear a ring every day, they rub against things, get knocked around. Eventually that seal breaks and the wood underneath is exposed to whatever you put your hands in.

I really genuinely believe that solid wood rings look really cool, but durability wise, I would not recommend one for daily wear.

Bentwood rings are stronger. You take a thin piece of wood, soak it, bend it around a form, and let it set. It's the way I inlay it into the tungsten nowadays, the grain runs continuous instead of being glued in chunks and it looks cleaner. But you run into the same problems eventually. The seal wears down, the wood gets wet and cracks. Bentwood rings take longer to make and they are still easier to break than you would expect.

Tungsten carbide is hard, very hard, it does not bend, absorb water or burn on the lathe. By encasing wood inside a tungsten core, the wood is protected and stays sealed. It never touches your skin or the things you touch during the day, the wood is just there to look beautiful, and the tungsten is there to make sure it lasts.

One day I want to make rings with a metal core and a wood exterior. I made a test version already and it looked great. Then I dropped it on pavement to test its durability and and the wood chipped. Was it fixable? yeah, I could have sanded it down and resealed it, but I do not want people to have to repair their rings constantly, I want to build something that lasts without needing constant attention.

Wood rings are absolutely beautiful, they just are not built for the long haul unless something stronger is backing them up. That is why every Neyu ring uses a tungsten core. The wood gets to be the star of the show, and the tungsten makes sure the show runs for a long time.
