Silver is one of the oldest, most valuable, and most prized metals in human history. Used since ancient civilizations for coins, jewelry, utensils, and medicinal purposes, silver continues to occupy a prominent place in the world of goldsmithing, technology, and decoration. In this article, we explore the main characteristics of silver, its uses, advantages, care instructions, and curiosities that make this metal so special.

What is Silver?

Silver is a chemical element with the symbol Ag (from the Latin "argentum") and atomic number 47. It is a transition metal with a white color and a characteristic metallic luster, highly malleable and ductile. It is found in nature both in its pure state and in ores, and is often mined along with lead, copper, and zinc.

Pure silver has greater electrical and thermal conductivity than any other metal, making it highly valued in industrial and technological applications.

How to Identify Genuine Silver

Look for the assay office mark:

  • 925: Indicates 92.5% pure silver
  • Official marking: A deer's head (Portugal) for silver

Other methods:

  • Magnet test (silver is not magnetic)
  • Oxidation reaction (genuine silver darkens over time)
  •  

Silver and Sustainability

  • Silver can be recycled indefinitely without losing quality;
  • Recycled silver jewelry is an environmentally friendly option;
  • Responsible and certified mining is essential to preserve natural resources.

Types of Silver Used in Jewelry

Although pure silver (99.9% silver) is too soft for use in jewelry, there are alloys with other metals that make the material stronger:

● 925 Silver (Sterling Silver)
Contains 92.5% silver and 7.5% other metals, usually copper. It is the most common type in jewelry and offers the ideal balance of shine, durability, and value.

● 950 Silver
With 95% pure silver, it is even more shiny but slightly less durable than 925 silver. Used in special and handmade pieces. 

● Alpaca or Germanic Silver
Contains nickel, zinc, or copper, but no silver. Despite its similar shine, it is cheaper and used primarily in costume jewelry.

Silver Care

Silver can oxidize (darken) over time due to reaction with sulfur present in the air or on the skin. To maintain its shine:

  • Store in a dry place away from direct light.
  • Avoid contact with perfumes, creams, or cleaning products.
  • Clean with a cloth designed for silver or with special solutions.

Difference between Silver, Gold-Plated Silver, and Oxidized Silver. 

Gold-Plated Silver: This is 925 silver with a gold coating, combining the shine of silver with the elegance of gold.
Oxidized Silver: The silver is intentionally darkened to create contrast and highlight design details.

These variations have gained popularity in contemporary jewelry.
