The blackened color of this metal indicates, precisely, that our jewelry is made of 925 Sterling Silver. 925 Sterling Silver darkens due to daily use, as well as for other reasons. One of the most common reasons is the use of products such as perfumes, shampoos or gels. It may also react immediately with corrosive or cleaning products. In addition, this metal can also become contaminated by reacting with small particles in the air, such as sulphur found in the atmosphere in the form of sulphide or hydrogen sulphide. And as an intersting fact! Silver is not darkened by "oxidation" (since it is a noble metal and cannot be oxidized), but it acquires that color by "sulfidation". Another factor to consider is the PH of our skin. If it tends to be acidic, there is more chance that the silver will turn black. That explains why your jewelry can tarnish faster than the jewelry of other people. It depends on the acidity of your skin.
