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 term "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 standardize trade and precious materials.
Among his measures, Afonso II decreed strict standards for the purity of metals used in coins and valuable objects. Silver that met these legal requirements — with a minimum purity level defined by law — came to be 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 recognized 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 jewelry 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 Recognize Sterling Silver?
In Portugal, sterling silver pieces are obligatorily subjected to assaying — a certification system managed by the Portuguese Mint and Official Printing Office (Casa da Moeda) and Assay Offices. The hallmark (mark engraved on the piece) guarantees the authenticity and purity of the metal. Learn more about our assay certification.
The main hallmarks to know:
- Guarantee hallmark — indicates the purity level (e.g., 925)
- Goldsmith's hallmark — identifies the manufacturer or artisan
- Date hallmark — records the year of assaying
Sterling Silver in Contemporary Jewelry
Today, 925 silver is the material of choice for quality artisan jewelry. Its versatility allows for combinations with natural stones — such as rose quartz, jasper, or mother-of-pearl — creating unique pieces that blend tradition and modernity.
At MÖHYA Signature, each piece is created in certified 925 silver, often combined with hand-selected natural stones. This is the case for the PRÏNCIPESSA Ring, with rose quartz, the DUÄLIS Ring, with red jasper, or the LÜX Pendant, with mother-of-pearl.
King Afonso II's legacy 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."
