I thought the article was excellent and gave a good overview of the alloys used in making jewelry. It was clear that gold had to be mixed with other minerals because it was not strong enough to use in jewelry in its pure form. It was not clear why platinum had to be mixed with other minerals in order to use it in jewelry, however. A good job was done in delineating the properties of the different platinum alloys, but the lay person was still left wondering why any alloy of platinum was needed in jewelry making.
I loved having a short, readable essay on precious metal available here on Pricescope. Thank you, John!
