In addition, the ring will be polished with rhodium in order to give it almost the same luster and appeal as to that of platinum.     White gold diamond ring designs became popular during the 1920s when romantic and stylish designs were more in vogue. In fact, many studies carried out in the diamond engagement ring field reported that most of the diamonds are during Art Deco and Victorian eras are made using white gold. There are many reasons for this, and one of the sound ones is the affordability of white gold metal when compared to other options such as yellow gold and rose gold. Apart from that, the malleability of white gold metal also makes it a popular option amongst couples who are in awe of complex detailing and design works.
