What is silver 925

Bizarre silver products are stamped with "925".
This display is limited to a silver content of 925/1000 (silver is expressed in parts per thousand), which is currently considered the most appropriate purity for silver products.
And silver products with this silver content are considered to be pure silver worldwide.
The number "925" refers to the silver content (purity), which means that it contains 92.5% silver. The remaining 7.5% is mixed with metals such as copper to form an alloy of copper and silver.
Generally, it is the material used for accessories called "silver".
Silver 925 is also known as "sterling silver", and many products are stamped with "STERLING", "SV925", and "925". STERLING has the meaning of "valuable" and "genuine".

-Why not make it with 100% silver?

Silver is actually very soft, making it a slightly unsuitable material for accessories.
Therefore, in order to make silver strong enough to be used as an accessory, it is mixed with other metals such as copper to form an alloy.
By making it into an alloy, silver gains strength and becomes hard enough to be used as an accessory in daily life.

About Ibushi

If silver is left alone, it will turn black by combining with sulfur components in the air.
This sulfur is also related to the fact that silver turns black after entering a hot spring.
Taking advantage of this property, silver is intentionally made black and then polished to create a three-dimensional effect, or to create an antique-like taste.
Care must be taken when cleaning accessories that have been oxidized, as the odor may be removed if the accessories are polished too much.

About plating

Bizarre's plated products are made by plating precious metal materials over 925 silver.
Bizarre mainly sells products with Ibushika black lute plating, but rhodium plating and gold plating are also popular.
Because it is coated with the original quality of the material, it is safe and affordable, and you can enjoy a wide range of designs and abundant color variations.
Polishing with a commercially available polish will remove the plating, so we recommend washing with lukewarm water.
