10. Sefinni’s advice

1. What is silver oxidation?

Oxidation is a natural chemical reaction that occurs when silver comes into contact with oxygen, moisture, sulfur or other chemical compounds from the environment. This reaction creates a thin layer of silver sulfate on the gemstone’s surface, leading to a color change.

This process does not mean the gem is broken or of poor quality – oxidation does not affect the structure of the metal and is 100% reversible.

2. How can you recognize oxidation in silver jewelry?

The visible signs are:

• Colored closure – from dark gray to matte black

• «dirty» appearance.as if the jewel had been forgotten in a dusty treasure chest

• Lack of shine – the gem appears dull, lifeless

• Localized areas: around stones, in cracks, inside chains or in incisions

Oxidation occurs especially for frequently worn jewelrybut it can also occur in stored ones, if left in contact with humid air, acidic skin or synthetic fabrics.

3. Why does silver oxidize?

Pure silver (Ag) is very soft, so jewelry is made from it 925 silver – an alloy with 92.5% silver and the rest other metals (usually copper). It is this alloy with which it chemically reacts sulfur compounds and with oxygen.

Factors favoring oxidation:

• pH of the skin – acidic skin accelerates chemical reactions

• Perfumes, creams, lotions – may contain aggressive compounds

• pollution – Urban air contains sulfur particles

• Incorrect storage – exposure to air, synthetic fabrics, plastic

• Chlorine or salt water – oxidation is rapid

• Contact with eggs, onions, garlic – rich in sulphur

• Excessive sweating

4. Oxidation and dirt: how is it distinguished?

It is important not to confuse oxidation with simple dirt.

5. How do you prevent silver from tarnishing?

While you can’t stop the process completely, you can slow down considerably:

✔️ Wear with care

• Apply perfume, cream or makeup Before to wear your jewelry

• Avoid wearing silver jewelry shower, swimming pool, sea, corridor

• Clean them gently with a soft cloth after each use

✔️ Store correctly

• In anti-oxidation bags or cotton bags

• Avoid cheap plastic jewelry cases – they trap moisture

8. Myths about jewelry tarnishing

❌ «Oxidized silver is not authentic»

False. Only real silver jewelry tarnishes. Those made of «stainless steel» or silver do not undergo the same process.

❌»Oxidized jewelery must be replaced»

False. Cleaning restores their original shine – and some controlled oxidation is also aesthetic (e.g. vintage style).

❌ «Oxidation is due to poor quality»

False. Even the highest quality 925 silver can tarnish – it is a natural process.

9. When should you call a jeweler?

• If the gem has sensitive stones or delicate media

• If the oxidation has penetrated deep into the texture of the engraving

The jeweler can clean the gem using special and safe procedures overpaintable with an antioxidant protective layer (rhodium or paint).
