I have been shopping with JTV for years & can tell you it is a "Hit & Miss" with them. I have purchased over 25 or more silver (?) gemstone rings from them and was happy until recently I looked in my jewerly box & saw that 4 of the rings looked horrible, they now have a blackish coppery look to the silver & my 3 stone apatite one has the stones now looking cloudy too! Awful! I tried washing them in soap & water, Nothing... Then I used silver/gemstone cleaner, still nothing. They are JUNK & one was one of my favorite Peridot rings! I trusted JTV but now I feel dupped by them! SO disappointed... About the hosts, I personally love them all ( with the exception of one lady who gets on my nerves) but now I will not believe them any longer... So if you want take your chance with JYV ~ you may get a nice quality item OR a Cracker Jack item...
