I purchased the sterling silver(supposedly)criss cross ring from Mobstub on the 31st of December 2016. I wore this ring approximately 7 or 8 times and the ring has already started to tarnish. When I complained to Mobstub the young lady that responded said that from time to time sterling silver will tarnish. Mind you I have several sterling silver rings and this has never happened. The ring is obviously not sterling silver but sterling silver coated. There are no scratches on the ring, it just faded in no time. This ring is rated by me a one star because I like the design but the ring is no good.
