Sterling Silver Necklace Extender

We use 925 sterling silver, which is a lightweight metal made of 92.5% pure silver. The remaining 7.5% comprises alloy, which makes our jewellery durable and perfect for everyday wear.

What to know about sterling silver jewellery 

• Proactive maintenance is the best way to prolong the lifespan of sterling silver.  
• Contact with perfume and cosmetic products can cause sterling silver jewellery to tarnish.  
• To mitigate against tarnishing, wear your jewellery often! The more you wear it, the less maintenance it needs.  

How to store sterling silver jewellery 

• If not stored properly, sterling silver jewellery can be prone to oxidising — this is the ‘tarnishing’ that you may experience.  
• We suggest that you do not store your jewels in our gift boxes long term. Keep your jewellery in a cool, dry place away from direct sunlight. 
• Store it with the anti-tarnishing tab that came with your purchase to protect against moisture during storage. 

How to clean sterling silver jewellery 

• Proactive maintenance is the best way to prolong the lifespan of sterling silver.  
• Clean by wiping with a soft, dry polishing cloth, or use a silver cleaner solution to soak the jewellery before buffing gently with a silver polishing cloth.  
• Ultrasonic cleaners are safe to use on silver jewellery.  
• Avoid using abrasive cleaners or brushes, as these can scratch the silver.
