What is 925 Silver and Why Is It Worth It?
If you're looking for jewelry and constantly see "925" or "Sterling Silver" marked, you might wonder what it means. This article answers all the basic questions—what it is, how to recognize it, how to care for it, and why it's worth choosing.
What Does "925" Mean?
The number 925 is the purity mark for silver. It means the metal consists of 92.5% pure silver and 7.5% other metals—usually copper.
This combination is not arbitrary. Pure silver (99.9%) is too soft to maintain its shape for everyday wear. The addition of copper makes it durable without losing its properties.
925 silver is an international standard. You'll find it engraved on the jewelry—usually in a discreet spot as a mark of authenticity.
925 Silver vs. Other Materials
925 Silver vs. Silver-plated
Silver-plated is an inexpensive base metal (e.g., copper or brass) that has been coated with a thin layer of silver. Over time, this layer wears off, and the base metal becomes visible. 925 silver is solid throughout its mass—it doesn't wear off.
925 Silver vs. Gold
Gold is more expensive and has a different aesthetic. 925 silver has a cooler, contemporary character that suits both casual and formal looks. For handmade jewelry, 925 silver is the material chosen by most modern Greek jewelers.
925 Silver vs. Stainless Steel
Stainless steel is durable and inexpensive but does not have the same value or feel as 925 silver. For a gift or a piece of jewelry to be worn with special significance, 925 silver is the clear choice.
Is It Hypoallergenic?
925 silver is generally hypoallergenic and suitable for sensitive skin. It rarely causes reactions—unlike jewelry of unknown composition, which often contains nickel.
If you have particularly sensitive skin, ask the jeweler about the alloy's composition. For high-quality handmade jewelry, the jeweler knows exactly what they use.
How to Recognize Authentic 925 Silver
Look for the mark. Authentic 925 silver has "925", "Sterling," or ".925" engraved in a discreet spot. If there's no mark, it's suspicious.
Magnet test. Authentic silver is not attracted to a magnet. If the jewelry sticks, it's not silver.
Buy from a reliable source. The best way is to buy from a jeweler you know and trust. A handmade jeweler working with 925 silver will always give you a guarantee for the material.
How to Care for 925 Silver
Silver tarnishes over time due to oxidation—this is natural and not a defect. Care is simple:
Daily use: Wear it regularly—contact with the skin helps maintain its shine.
Storage: Store it in a closed pouch when not wearing it.
Cleaning: Wipe regularly with a soft cloth. For more intensive cleaning, use a special silver polish or simply warm water with a little soap and a soft brush.
What to avoid: Chemicals, bleach, swimming pools, and perfumes directly on the jewelry accelerate oxidation. Take off your jewelry before swimming or doing chores with chemicals.
Why Handmade 925 Silver Specifically?
925 silver is an excellent material—but when combined with handmade craftsmanship, the result is in a different league from industrial jewelry.
In handmade jewelry, each piece is the result of hours of work and personal expression. No two are identical—even if they have the same design, small differences in the creator's hand make them unique.
In the workshop of Platon Vasatis, every piece of jewelry is made from 925 silver in Athens. The aesthetic is organic—inspired by flow, movement, and the Greek tradition in art. See the collections here.
