Technically there is no reason why a silver cladag ring cannot be made with just about any gemstone. The RG174 image shows a silver cladag ring with a moonstone. However, there is one important thing that you should bear in mind when choosing a sterling silver cladag ring. All silver jewelry will tarnish, no plating on silver is a permanent anti-tarnish solution. The good thing is that tarnish if cleaned at the outset will not diminish the beauty of your silver cladag ring. Recommended liquids and polishing cloth are available to polish tarnish off silver jewelry.
However, the important thing to understand is that not all gems have the same properties. Certain gems like emeralds might be affected with the chemicals used to clean your tarnished silver cladag ring. You should therefore discuss the properties of your preferred gem stone before purchasing a silver cladag ring. The moonstone shown above is a good gemstone option for a sterling silver cladag ring. You can polish the silver moonstone ring and then rinse it in cool clean water to wash away any residue chemicals that might be stuck to the ring.
