There are only eight metals deemed precious: silver, gold, and the six metals of the platinum family (platinum, palladium, rhodium, ruthenium, iridium, and osmium). Though these are the official precious metals, non-precious metals can be mixed with the the precious metals to create new and appealing variations. Just like the recipe book analogy, low fat alternatives vs low carb, the metal recipes provide tradeoffs as well.
