“S925” is a marking commonly found on jewelry, particularly on silver jewelry, and it indicates that the item is made of 92.5% pure silver. 

The “925” represents the silver content, which is equivalent to 92.5% silver, while the “S” typically denotes that the piece of jewelry is made of sterling silver. 

What Is The Difference Between S925 And 925?

There is no difference between “S925” and “925” in terms of their silver content. Both markings indicate that the jewelry is made of 92.5% pure silver, which is commonly known as sterling silver.

The “925” represents the silver purity, meaning that the jewelry is composed of 92.5% silver and 7.5% of other metals, typically copper, which is added to enhance the strength and durability of the silver. 

The number “925” is derived from the fact that sterling silver contains 925 parts of pure silver out of 1000 parts total.

The “S” that is sometimes included before the “925” is used to denote that the jewelry is made of sterling silver. It is a common practice to use the letter “S” as an abbreviation for “sterling” to indicate the type of silver used in the jewelry. 

Is S925 Worth Anything?

S925” refers to the silver purity of jewelry, indicating that it is made of 92.5% pure silver, which is commonly known as sterling silver.

As such, the intrinsic value of jewelry marked as “S925” lies in the silver content.

The value of sterling silver jewelry, including those marked “S925,” is typically determined by several factors, including the current market price of silver, the weight of the silver in the jewelry, the craftsmanship, brand, and overall condition of the piece. 

Sterling silver jewelry is generally less expensive than precious metals like gold or platinum, but it can still hold value as an investment or be valuable for its aesthetic or sentimental worth.

Will S925 Turn Your Finger Green?

One of the most common reasons for a finger turning green when wearing silver jewelry is a reaction between the metal and the acids or chemicals present on your skin, which can create a harmless reaction that leads to temporary green staining. 

This can happen due to factors such as your individual body chemistry, perspiration, and exposure to substances like lotions, soaps, or other chemicals.

It’s also worth noting that some sterling silver jewelry may be plated with other metals, such as rhodium or nickel, to enhance its appearance or provide additional protection. 

If you have a sensitivity or allergy to these metals, it’s possible that wearing plated sterling silver jewelry could cause skin irritation or discoloration.

  • Check for tarnish: Sterling silver naturally tarnishes over time when exposed to air and moisture.
