BAD QUALITY JEWELLERY

Beware of the rings that you buy from them, the stones dont seem to be of a good quality, I purchased a tanzanite ring for my wife, she used it for a week and packed it away as it was loose only to find out that when she wanted to use it again, that the stone has faded, we took it back to the sandton store, the mangeress said she suspects that it was caused by lotion and she needs to send it in to have it checked, a week later, head office also gave the same report that it was due to lotion which is utter nonsense and this all happened within a month and a half of purchase, we have asked them to either refund or exchange the ring and have not heard back from them in the past 3 weeks.
