It will go through the pros and cons of the silver alloy and especially 925 sterling silver which is the highest quality silver in the jewelry field.


Why are they mixing silver with other metals?

Pure silver is an extremely soft material and therefore not suitable for practical everyday use in the delicate form of jewelry.

This is the reason it is costumed to mix it with other metals.

The term silver 925 indicates the degree of purity – 92.5% silver in the alloy (or 925 out of 1,000).

In means of jewelry manufacture, it is costumed to mix silver with copper and sometimes with zinc or platinum but as long as the silver percentage is 92.5% it will be called silver 925 or by its prestigious name – sterling silver.

According to most, it is better to purchase silver 925 since the chance of finding nickel is extremely low in comparison to other silver alloys.

Nickel, for anyone who doesn’t know, is actually the metal responsible to all the allergic reactions and the uncomfortable sensation that jewelry may cause.

In fact, up to 10% of the world’s population is suffering from insensitivity to nickel from mild to severe severity.

Nowadays the regulations in most of the world for using nickel are extremely strict, but there is still a risk when buying cheap jewelry.


Coating of silver 925


Obviously, silver is being covered by gold or black radium in order to produce different appearance.

Silver jewelry with gold or other coatings has a bad reputation in some countries.

The reason is that many of the traders and importers choose to sell silver jewelry with very thin coating of 0.3 micron at the very best.

Our standard in Dianoche for gold coating is a full one micron!

This is a relatively thick coat of gold and therefore the color will be preserved for longer time and the jewelry will look as a gold jewelry.

We strongly recommend you take the coating thickness under consideration while purchasing.



Why silver gets discolored?

One of the things that annoys most of the people wearing silver jewelry is the fact that in most of its purity levels silver gets discolored.

The reason that silver gets discolored is an oxidation reaction while coming to contact with air.

Air is well known to contain some substances as sulfur (phenomenon that becomes more common since the world became more industrialized and cars are more common…) and the metal reacts to that as one of its features.

This reaction produces sulfuric silver.

There are some who like the old fashion look but for those who doesn’t, here is a simple way for cleaning silver.

We personally deal with immediate discoloration by coating our jewelry with radium or gold, but this solution has an expiration date since the coating is pilled off with the passing years….



How to clean discolored 925 silver?

Cleaning silver is relatively simple, and the results are excellent.


  1. Baking soda or soda powder.
  2. Boiled water.
  3. A bowl that can contain boiling water.
  4. Tin foil – the one found in every kitchen.
  5. Cloth / paper towel / towel.

Put the tin foil at the bottom of the bowl with the shiny side up.

Scatter soda powder or few teaspoons of baking soda over the tin foil.

Place the silver jewelry.

Poor the boiling water.

Wait for 30 sec until the brightening of the silver is apparent.

Pull the silver out than dry with the cloth.


*Pay Attention – we are not taking responsibility for any damage that may occur to gems inlayed in the jewelry.

Mostly there are no problems but some stones, pearls for example, may be damaged due to their delicate nature.

Follow the instruction under your responsibility only.
