Platinum is the rarest and sturdiest of all jewelry metals. The purity of this metal makes it naturally hypo allergenic which is good for people with sensitive skin. As a result of the density of this metal makes it the most secure metal for setting gems in. It also has a naturally white color therefore it will not need plating or fade. Over time there will be natural wear and tear such as patina or minor scratches. The best way to clean platinum is warm soapy water and a soft brush.
Gold is the softest of all precious metals used for jewelry, but will not rust, tarnish or corrode. The metal is naturally yellow, but depending on the percent and type of alloys mixed in, the color can be changed to white or rose. Pure gold is too soft to be worn so it is necessary that it be mixed with alloys to make it stronger. Since gold is mixed with alloys the different levels of purity are refer to by Karatage (K) and expressed in 24ths. The two most common types of gold used for jewelry are 14K (58.3% gold) and 18K (75.0% gold). Gold is affected when in contact with harsh chemicals, so it is recommended to take off your jewelry before using chemical products.
Palladium has a strong resemblance to platinum. They both are naturally white in color, but palladium is stronger and lighter. It is part of a family of metals called “Noble Metals” because it does not corrode or oxidize. This metal is hypoallergenic since it is 95% pure and is not mixed with alloy metals or plated.
