One of the biggest complaints I get is the ring must be cheaply made-it turned my finger green. It can't be real gold or silver because my finger is turning green. But is it really the ring or could it be the chemistry of your body or the lotions, soap or chemicals you come into contact with on an everyday basis. The research I have done on this problem says that it can be contributed to your body chemistry, i.e. the acidity of the wearers skin, also lotions, soaps or every day chemicals that the wearer comes in contact with.
      10KT Gold, 14KT Gold, 18 KT Gold etc, is still only a gold alloy; gold mixed with other metals to form a piece of jewelry. In its pure form gold is quite a soft metal. It is combined with other metals to give it more durability. 24KT Gold is pure gold, 18Kt Gold is 18 parts gold, 6 parts another metal, 14KT Gold is 14 parts gold and 10 parts something else. And so on. Gold by nature is yellow in color. So to get a gold metal that is white in color the other metals added needed to help decrease the yellowness of the gold. Some of the metals used for this purpose are nickel, platinum, rhodium, and yes sterling silver. Even when this is done there is a yellowish tinge that is seen. To eliminate this a rhodium finish is applied to give the ring the true white color. This should also keep the wearers skin from contacting any material that could react adversely to their body chemistry.
      If the rhodium finish should wear away the other metals in the alloy can be exposed to elements somewhat caustic in nature to the metal.  The supplier I get my inventory from has put a lifetime guarantee on this and the material and workmanship of teh rings I receive from him.  Should problems arriseI recommend sending the ring with the guarantee certificate to him for a replacement. The address and directions are on the little card that is sent with the ring. If you have misplaced the card send me your address and I’ll mail you another one. Hope this has answered some of your questions. If not let me know and I’ll try harder.
