I have expanded my jewelry making to include earrings. After 35 years, I have re-pierced my ears. Years ago, I couldn't find anything thing to put in them that did not cause some kind of reaction. I am sensitive to nickle and find I can wear silver with no problems, gold even affected me. I haven't reacted to the copper ones I have made so far. Copper is readily available and so much fun to work with.
Found the turquoise in Arizona at some of the rock and gem shows we went to on your winter trip there earlier this year. I must have lost a few beads on the blue and white ones, they aren't even anymore, easy to fix.The little ones are bent out of shape but I'll re-bend them the next time I wear them.
