Palladium, one of the rarest metals in the world, is a member of the Platinum Group Metals. These metals are also referred to as "Noble Metals" due to their superior ability to withstand corrosion and oxidation. Palladium, which is listed on the Periodic Table of elements, is lighter in weight than its sister metal, Platinum. A naturally white metal, Palladium is hypoallergenic, will not tarnish and remains white forever. Palladium is 95% pure when used in jewelry, is extremely durable and does not require alloy metals and/or plating for protection, which ensures that it will remain white as long as you own your jewelry.
