What is a Precious Metal Fineness Mark
A fineness mark is an indicator of the percentage of pure precious metal in an alloy. It shows what proportion of pure silver is in an item, with the remainder being other, less valuable metals.
For example, one of the most common fineness marks is 925. This means that the alloy contains 92.5% pure silver. The remaining 7.5% consists of impurities, usually copper and other non-precious metals, which are added for strength and durability.
Differences Between Silver and Gold Hallmarks
Hallmarks for silver and gold have significant differences that make them easy to identify. The main distinctions lie in the shape of the hallmark itself and the numerical fineness values.
- Hallmark Shape: One shape of hallmark is used for silver, while a completely different one is used for gold.
- Numerical Values: Fineness marks typical for silver are not used for gold. For example, you won't find values like 800, 830, 875, or 925 on gold items.
Common Silver Fineness Marks and Their Uses
| Fineness Mark | Primary Use |
| 800 | Found quite rarely. |
| 830 | Mainly used for making silverware. |
| 875 | Used for silverware, and also often for gold-plated items. |
| 925 | The most common alloy for jewelry, known as "sterling silver". |
There are several standard silver fineness marks, each with its own primary area of application. The appearance and properties of the item depend on the fineness value.
Types of Hallmarks and Rare Fineness Marks
The image on a hallmark can indicate the period when the item was made. Soviet hallmarks feature a five-pointed star with a sickle and hammer inside. Modern Russian hallmarks depict a woman's head in a kokoshnik.
Sometimes, you may encounter rarer, more "exotic" fineness marks. These include, for example, 916 or 84. These are old fineness formats, particularly the zolotnik system, which was used in the past. Such hallmarks can be found on antique jewelry or silverware.
