This item was created with jewlery owned by my husband's grandmother. She has it put together by a professional artisan in California.  In mid-1970, with jewlery, she owned and was gifted or inherited. Her jewlery was not junk jewlery or broken or lost pieces.  She gathered some of her favorite pieces to have this made. I do not have any information on the jewlery used.  Mixed materials. As is.  Very good condition, no missing pieces on this tree.  Beautifully made.  This is just one jewlery framed art that was made for her (husband's grandmother).  If we didn't have more, I wouldn't let this peice go. (One of a kind).
