| What Is Platinum? Platinum is a group of metals known as the Noble metals, for their high resistance to wear and corrosion. The most popular and well-known platinum metal is called 950 Platinum. The 950 refers to the purity of the metal. Until recently, it was the only platinum metal available for use in casting jewelry, so it's what people think of when they think of platinum. Platinum group metals are completely hypoallergenic and will never turn yellow or tarnish. Platinum is more expensive than gold, but well worth the extra expense. Platinum metals are superior in hardness to gold, a more durable metal than gold, and have a harder finish that is less likely to scratch. Platinum is whiter than the traditional rhodium-plated white gold, will never tarnish, and is completely hypoallergenic. 950 Platinum is one of the world’s rarest metals. In the 18th century, King Louis XV declared that platinum was the only metal fit for a king. |
