An example would be if you see "825" stamped on a silver ring that means the ring has had 825 parts of pure silver, or more broadly 800 parts of pure silver. This is a larger part of a metal hallmark system of stamps and marks that indicate to what degree the composition of jewelry contains silver—percentages of the alloy. Specifically, 825 represents an alloy containing 82.5 percent pure silver with 17.5 percent other, usually copper, metals. Sometimes 'European silver' or just 'sterling silver' refers to this grade of silver.
Here, you would like to know the full understanding of "825" when there is a silver ring, first let me explain the meaning of "825", the process of adding silver, compare other silver grades, and the benefits and disadvantages of using this type of silver.
Due to it being beautiful, lustrous and malleable, silver is a precious metal used widely in jewelry. Pure silver (99.9% purity), however, is far too soft for everyday jewelry use. Silver, of course, is alloyed with other metals to make it durable and functional for daily wear, usually copper. This combination brings its strength, while preserving its aesthetic qualities.
The "825" number is a symbol that marks the silver content by way of parts per thousand. Specifically:
Silver is made up of 82.5 silver out of every 100 asked for in solid silver.
The other metals, which increase durability and wear resistance, make up the other 17.5%.

Silver 825 jewelry wears well and provides a good balance of durability and affordability while serving as the right size and color for the most striking effect. Here are the key reasons why this purity level is used:
Silver has the advantage of being soft, but not soft enough for it to be pure and also very prone to damage. The hardening of 17.5 % other metals, commonly copper, increases the resistance to scratches and deformation in 825 silver. Rings are particularly susceptible to damage and this is especially important.
Due to the fact that it has a bit less of the pure silver than 925 sterling silver, 825 silver is cheaper, but just as bright and polished. Which makes it an ideal option for budget buyers.
In spite of the fact that 825 silver is not quite as pure as 925 silver, it still retains the impressive brilliance and luster which make silver silver. It can be polished to a high shine and is visually identical to high purity silver to the untrained observer.
As long as your craft design has been created as an intaglio, the alloy is malleable enough to create intricate designs while strong enough to retain its shape to wear as rings, bracelets, pendants and earrings.
This type of silver can easily be identified by the "825" stamp. However, if you're unsure about the authenticity of the hallmark, you can confirm it through these methods:
If there is any "825" marking on the indentation on the inner band of the ring, or you cannot find it, look elsewhere. Jewelers show proof of purity stamps on their pieces.
Silver is not magnetic. If the ring is drawn to a magnet, the percentage of base metals may be as high as that it will not be genuine silver.
Silver purity can be tested for with nitric acid. Real silver, when applied to the metal, will react creamily white.
Advanced tools can verify your ring’s silver content by a professional jeweler.
Silver jewelry, including rings stamped with "825," offers several benefits:
