Silver has been a prized metal throughout history, not only for its beauty and malleability, but also for the results achieved when working with it. It has always been highly valued for creating objects, utensils, and jewelry. Its durability means that, today, antique or vintage jewelry, as well as accessories from bygone eras, are highly valued. However, it is important to know that pure silver is too soft to make durable pieces, so it is mixed with other metals to improve its strength. These alloys are known and classified according to the purity of the metal.

What is sterling silver?

Sterling silver, also known as 925 silver, is an alloy composed of 92.5% pure silver and 7.5% other metals, usually copper. This combination provides the hardness necessary for the manufacture of jewelry and decorative objects, while maintaining the shine and beauty characteristic of silver. Although alloys with 95% silver (950 silver) are occasionally found, 925 silver is the most common.

Pure silver is too soft to be used in jewelry, so it's mixed with other metals to improve its strength and durability. This alloy, known as 925 sterling silver, is widely used in jewelry and decorative objects due to its perfect balance of purity and hardness.

It's important to note that 925 sterling silver maintains the shine and appearance of pure silver, but with greater strength, making it a popular choice for creating durable, high-quality pieces.

Additionally, 925 sterling silver is hypoallergenic, meaning it is unlikely to cause allergic reactions in most people.

Throughout history, various silver alloys with varying degrees of purity have been used, adapting to the needs and preferences of each era and region. During periods of shortage or for economic reasons, silversmiths adjusted the combinations according to circumstances. Below are the main alloys and their names in different countries:

Main Silver Alloys and their Calibers

Fine Silver (999): Composed of 99.9% pure silver, it is extremely malleable and therefore rarely used in jewelry, as pieces can easily deform. It is commonly found in the form of ingots and coins. Although this is the purest, other alloys also exist with varying degrees of purity.

Sterling Silver (925): With 92.5% silver content, it's the most common alloy in jewelry due to its balance of purity and durability. This alloy contains 7.5% other metals, usually copper, which gives it greater strength without compromising its characteristic shine. In addition to this, other alloys such as 950 and 900 silver are used in different contexts.

950 Silver: This alloy contains 95% pure silver and 5% other metals, most commonly copper. It's prized in jewelry for its high quality and durability, making it ideal for making fine pieces like engagement rings, necklaces, and bracelets. Although it's popular, other alloys such as 960 silver and 935 silver are also available.

Sterling Silver (800): Contains 80% silver and 20% other metals. Although it is more durable than fine silver, its lower silver content makes it less valuable and less commonly used in fine jewelry. It is common in flatware and decorative objects. In addition to this, there are other alloys with different percentages of silver, such as 835 and 830 silver.

Denominations of Silver in Different Countries

Britannia Silver (958): Introduced in England in 1697, it contains 95.8% silver and was used as a standard for coins and valuables. Although it is one of the most recognized, other British alloys also exist with varying degrees of purity.

French Silver (950): This standard refers to a 95% silver alloy, common in high-quality French silver objects. However, other standards, such as 800 and 925 millesimals, are also used in France.

Russian Silver (Zolotnik): The Zolotnik system is an old Russian measure of purity. Zolotnik 91 (947) corresponds to approximately 94.7% purity. Zolotnik 88 (916) has a purity of approximately 91.6%. Zolotnik 84 (875) corresponds to 87.5% purity and was common in early Russian silverware. In addition to these, other less common gauges existed in Russian silverwork.

Scandinavian Silver (830): With a purity of 83%, it is typical of silver pieces from Scandinavian countries. Although this is the most recognized standard, other alloys with varying degrees of purity have also been used in the region.

German Silver (800–835): German silver typically has a purity between 80% and 83.5%, and is used in cutlery and decorative objects. In addition to these, other alloys with varying percentages of silver have also been used in Germany.

Silver Coins (750–900): Silver coins have historically had varying purities, usually between 75% and 90%, depending on the country and period. In addition to these ranges, other specific alloys have been used for coinage in different regions and periods.

These designations reflect the cultural traditions and legal standards of various nations, adapting to the desired properties of the final pieces and local regulations.

Silver in the economy and historic mines

Silver has played a crucial role in the economies of many countries. During the Spanish Empire, silver mines in the Americas, especially in Potosí (present-day Bolivia) and Zacatecas (Mexico), were crucial to the Spanish economy, financing wars and territorial expansion.

Today, countries like Mexico and Peru remain leaders in silver production, with iconic mines that continue to contribute significantly to their economies.

Pure silver and its use in jewelry

Silver ingots, usually 999 pure, are primarily used as investments and in industrial applications. However, for jewelry making, pure silver is too soft. Therefore, it is alloyed with other metals to increase its hardness and durability, resulting in alloys such as 925 silver, ideal for creating high-quality pieces.

Marks and stamps on silver

To guarantee the authenticity and purity of silver pieces, it's common to find hallmarks or stamps. The 925 stamp is the most common, indicating that the piece is made of 92.5% pure sterling silver. Other stamps may include the manufacturer's name, hallmark, or hallmark, as well as official marks certifying the metal's quality according to the regulations of the country of origin.

This information is invaluable to collectors, who in many cases become intrepid researchers. Through books, museums, and their own knowledge, they are able to determine the origin, year, manufacturer, and type of silver of a piece. All these stamps become a kind of "barcode" that ultimately builds the history of that piece, object, or jewel.

In short, sterling silver, especially 925 silver, has been and continues to be a fundamental material in the creation of antique and vintage jewelry, prized for its durability, beauty, and historical value. Understanding the different types of silver and their characteristics allows us to further appreciate these unique pieces that have endured over time.
