I bought item DOCZ695. Beautiful blue opal with spinal band. About 3 mos. Ago. Not long after it went from blue to green. And I mean green. Should I call Customer Service ( its been about 3 mos.) I'll even send back for exchange. I. really do love your jewelry, so don't take this as me being nasty, just disappointed. They are even posting it today for promo. For JTV. Elyce O'Leary in Penna.
