@jlknight65 – I appreciate the information about oiling vegetable ivory, too. Our son spent some time in Micronesia where the Caroline Ivory Nut Palm grows. He brought home some beautifully carved pieces.
Although it is jewelry, he bought the pieces as keepsakes so he doesn’t wear them. I asked him about oiling it and he wasn’t aware that it would need it, either.
After not being able to find any specific information about the care of these pieces we thought maybe a very light rubbing of organic coconut oil would be good since it is natural and has no additives.
I would love to know if anyone has more specific information.
