Magnesium and palladium are both metals; they both have the usual silvery appearance of metals, and are both very electrically conductive. Other than that they are very different. Magnesium is soft and reactive, palladium is hard and inert.
Hard
This is a partial quote from the Wikipedia, "Palladium, along with platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Platinum group metals share similar chemical properties, but palladium has the lowest melting point and is the least dense of these precious metals." Please see the related link for more information on palladium. You may want to contact a jeweler for a price per ounce comparision with platinum. You can avoid manually calculating the value of palladium if you have an iPhone or iPod by using an app called Pennyweight. Simply entering the weight and selecting the purity will automatically calculate the value of palladium based on the current market price.
