The History of Sterling Silver: From Medieval Origins to a Symbol of Quality

Silver has always held a prominent place in human history — as currency, adornment, and a symbol of power. But the expression "sterling silver" has a very specific origin, rooted in the history of Portugal and the reign of King Afonso II.

The King Who Regulated Silver

In the 13th century, Portugal was a young kingdom, still consolidating its borders and institutions. King Afonso II (1185–1223), the second king of Portugal, was known not only for his military campaigns but especially for his administrative and legislative vision. He was the first in Portugal to establish laws and regulations to standardise trade and precious materials.

Among his measures, King Afonso II decreed strict standards on the purity of metals used in coins and valuables. Silver that met these legal requirements — with a minimum purity content defined by law — became known as "sterling silver". The name is not a metaphor: it is a direct reference to the fact that its quality was guaranteed by the law of the kingdom.

What Defines Sterling Silver?

Over the centuries, the concept evolved and was adopted internationally. Today, the most recognised sterling silver is 925 silver, also known as sterling silver, composed of:

  • 92.5% pure silver
  • 7.5% other metals (usually copper), which provide strength and durability

This alloy is the standard used in quality jewellery worldwide, including MÖHYA Signature pieces. 100% pure silver would be too malleable for everyday use — the addition of copper ensures that pieces maintain their shape and shine over time.

How to Recognise Sterling Silver?

In Portugal, sterling silver pieces are obligatorily submitted for assay — a certification system managed by the Portuguese Mint and Official Printing Office (Casa da Moeda) and Assaying Offices (Postos de Contraste). The hallmark (mark engraved on the piece) guarantees the authenticity and purity of the metal.

The main hallmarks to know:

  • Purity hallmark — indicates the purity content (e.g., 925)
  • Goldsmith's hallmark — identifies the manufacturer or artisan
  • Date hallmark — records the assay year

Sterling Silver in Contemporary Jewellery

Today, 925 silver is the material of choice for quality handcrafted jewellery. Its versatility allows for combinations with natural stones — such as rose quartz, labradorite, amethyst, or turquoise — creating unique pieces that blend tradition and modernity.

At MÖHYA Signature, each piece is created from certified 925 silver, often combined with hand-selected natural stones. The legacy of King Afonso II lives on in every hallmark — a guarantee that what you wear is genuine, durable, and made to last.

"Sterling silver is not just a material. It is a promise — the same one made eight centuries ago."
