Jewelry, everyone loves. But do you know what is the 925 Silver? 925 pure silver means the silver productions which's purity of silver are 92.5%. 925 here represent the purity of silver. This is required lowest purity of silver productions while the purity of 999 gold. For foot silver is too soft and it's easy to be oxidized, since Tiffany & Co. created 925 silver, it's thought to be the lowest standard of pure silver.
Because of the features of silver itself, 100% pure silver cannot be used in making jewelry as it is extremely malleable and it can suffer damage easily. It also tends to get very soft, even in conditions of normal temperature. That is why 925 Silver is used and not the pure form of the precious metal.
The method craftsmen use to increase the strength of the metal consists of adding other materials to silver. The life span of the jewels made of silver depends on this process, as problems like malleability and softening can make them break apart. By combining pure silver with alloys, the craftsmen make pieces of jewelry that are more resistant to scratching and damage.
One of these combinations is the one known as 925 Sterling Silver. It is a blending mix obtained from 92.5% silver and 7.5% copper. Copper is not always used by craftsmen and it can be replaced by other metals or combinations of materials. This is considered the best choice as copper is cheap and the refining techniques have improved during the last years.
By adding copper to silver, craftsmen have managed to obtain a highly reliable alloy that is successfully used in the jewelry industry. The combination is very popular as the silver craftsmen can make earrings, rigs, bracelets and other pieces of silver jewelry, knowing that their work will be resistant and durable.
Silver is a kind of active metal, and it's easy to make chemical reaction with the sulfur in the air so that the silver productions will become black. As you can see, we should let the silver accessories touch with air less when wearing, and should not wear it in a place with strong chemical gas. After touching sulfur soaps, you must dry it at one. Also the chloride in the sweat of body also influences the silver.
So, as a customer, it is good to know if the silver jewel you purchase is made of 925 Sterling Silver. A way to verify this is by checking the jewels hallmark. Usually, the 925 Silver jewelry is almost entirely hallmarked. For instance, the tiffany silver jewelry with all the hallmarking requirements.
