- Platinum -

Platinum is frequently used in the finest jewelry and to set the most valuable gems because it's more workable and easier to move the prongs or settings around the stones. Such advantage reduces the risk of accidental damage to the setting.

Long a favorite for classic looks and for the finest diamond settings, platinum is now evolving as the metal of choice for new design trends. Many sleek, bold, contemporary fine jewelry pieces are made based on this precious material. Platinum is often alloyed with other metals to create interesting colors.

Comparing to gold, platinum is even more rare and valuable than gold. Platinum is actually composed of the following 6 elements that are found in nature:

Rhodium
Iridium
Palladium
Osmium
Ruthenium
Platinum

Platinum is the purest material there is and it rarely cause allergic reactions to human skin. Unlike gold, platinum is not identified by "karat" marks. The abbreviation PT or Plat are commonly used in the United States to indicate the platinum and its purity content. 1000 point is the 100% purity. So for example, PT950 means, the purity is 950 / 1000, or 95% pure.
