Key Facts About Platinum
Platinum stands out among precious metals used in jewelry for several significant reasons. Its characteristics make it a durable and desirable choice for engagement rings, wedding bands, and other fine pieces.
Properties of Platinum
- Hypoallergenic: Due to its high purity, platinum is hypoallergenic, making it an excellent choice for people with sensitive skin or allergies to other metals like nickel, which is sometimes found in white gold alloys.
- Naturally White: Platinum is a naturally white metal. Unlike white gold, which is often plated with rhodium to maintain its white appearance, platinum retains its color over time.
- No Re-Plating Needed: Because it is naturally white and doesn't lose its color, it won't need to be re-plated like white gold to maintain its bright white finish. While platinum can develop a natural patina over time (a subtle dulling of the surface), it's the metal moving, not wearing away.
- Durability: Platinum is exceptionally dense and durable. While it can scratch (producing the patina), it doesn't wear away like other metals, meaning the volume of the metal remains largely unchanged over time.
Historical Context
Platinum has a history stretching back centuries.
- Ancient Use: It was used by the pre-Columbian Indians of South America long before its properties were recognized elsewhere.
- Western Discovery: Platinum wasn't noticed by western scientists until 1735, significantly later than gold and silver.
Sourcing
- Mining Location: The majority of the world's platinum supply comes from a specific region. About 80 percent of platinum is mined in South Africa. Other significant sources include Russia, Zimbabwe, Canada, and the United States.
