Nickel Allergy - need new wedding band

During my pregnancy I developed a nickel allergy, and can no longer wear my wedding band. Luckily it is just a plain gold wedding band, nothing with huge jewels! My husband would like to buy me a new wedding band, one made from something natural that won't irritate my skin ( i have a lot of man-made allergies)

I've been looking on ebay and etsy, and can't really find anything I like. Do any of you know a company, supplier, creative person, who makes rings from bone, shell, or anything else natural and lasting? Am open to material suggestions!

 

My mother in law can't wear her gold wedding band either due to metal allergies...but she can wear silver.
Maybe you could find a really nice silver ring?

 

After much searching, I found a plain hardwood band in my ring size on ebay. Also found a coconut ring in my size on ebay that will be shipped to me from Hong Kong. I bought both, as they were about $5 a piece.

I thought about silver, but I am really really pale skinned, and silver tends to wash me out. Also, am just not all that into metal jewlery in the first place, so I think that the wood will suit me more!

Thanks for the input though, and drumminmama, that site is pretty nifty!
