I was lucky enough to visit Namibia north of South Africa on the west coast recently. There were a couple of really good jewellery shops that drew my attention of course. I found it interesting in one shop that the White Gold was not Rhodium plated which is the treatment used extensively to give it that shine. With a Yellow & White Gold ring when not plated the contrast was much better and no further treatment was needed every few years. I think this is a really good idea!
