A platinum ring typically contains a high percentage of platinum combined with smaller amounts of other metals.
Composition of Platinum Rings
The composition of platinum in rings varies, with two common alloys used in jewelry. Here's a breakdown:
-
950 Platinum: This is the most common standard for platinum jewelry. It consists of:
- 95% Platinum
- 5% Cobalt or Palladium
The hallmark "950 platinum" indicates this composition.
-
900 Platinum: Another less common alloy used is composed of:
- 90% Platinum
- 10% Other Metals
The hallmark "900 platinum" indicates this composition.
| Alloy | Platinum Content | Other Metal Content | Hallmark |
|---|---|---|---|
| 950 Platinum | 95% | 5% (Cobalt or Palladium) | 950 Platinum |
| 900 Platinum | 90% | 10% (Other Metals) | 900 Platinum |
These alloys are chosen to create jewelry that is durable while maintaining the desirable qualities of platinum. The addition of other metals increases the strength and workability of the pure platinum.
