Understanding Precious Metals
What Makes a Metal Precious?
Precious metals are rare, naturally occurring metallic elements that have high economic value. They are distinguished from base metals by their:
- Rarity in the Earth's crust
- Resistance to corrosion and oxidation
- Lustrous appearance
- Malleability and ductility
- Historical use as currency or store of value
Purity Measurements
The purity of precious metals is measured using different systems:
- Karats: Used for gold, with 24 karat being pure gold (99.9%)
- Fineness: Expressed in parts per 1,000 (e.g., 925 silver is 92.5% pure)
- Millesimal fineness: Similar to fineness but expressed in parts per 1,000
- Sterling standard: Specifically for silver, indicating 92.5% purity
Hallmarking: Ensuring Authenticity
Hallmarking is the official marking or series of marks applied to precious metal items to certify their purity. The practice dates back to the 14th century and continues to be an important consumer protection measure today.
Standard Marks
Indicates the purity of the metal, such as 925 for sterling silver or 750 for 18K gold.
Maker's Marks
Identifies the manufacturer or company responsible for producing the item.
Assay Office Marks
Indicates which office tested and marked the piece, often represented by a symbol.
