When it comes to jewellery, very few materials can compete with the timeless elegance of gold. From beautiful earrings to stunning rings and delicate necklaces/bracelets, gold has been adored and cherished for centuries. One particular gold alloy that strikes a perfect balance between durability and affordability is 9ct gold. In this blog, we will delve into the fascinating world of 9ct gold, uncovering its creation process, unique properties, and why it's the perfect choice for your favourite jewellery pieces. 

What is 9ct Gold?  

At NJO, our 9ct gold pieces are made to last forever. 9ct gold is made of 37.5% gold mixed with an alloy of other metals. The term "9ct" refers to the gold's purity, indicating that it contains 9 parts gold out of a total of 24 parts. The remaining 14 parts consist of different metals, typically copper, silver, or zinc, which are added to enhance the gold's strength and durability. 9ct gold will not oxidize, so you can wear your NJO pieces every day, every way. All of our 9ct gold pieces are hallmarked with '375'.  

The Creation of 9ct Gold 

To create 9ct gold, pure gold is carefully blended with other chosen metals. The alloying process is crucial, as it determines the final colour, and properties of the gold. A blend of copper and gold tends to give a warm, reddish hue, while a silver or zinc blend contribute to a paler, yellow appearance. 

After the metals are mixed, the resulting alloy is heated to a high temperature and then shaped into various forms. From there, the forms are further manipulated and crafted into exquisite jewellery pieces. At NJO, our 9ct gold collection contains earrings, rings, necklaces, and bracelets. 

The Advantages of 9ct Gold  

9ct gold has many advantages, the main one being its affordability. Compared to higher purity gold, such as 18ct or 24ct, 9ct gold offers a more budget-friendly option without compromising its beauty or durability. This makes it a popular choice amongst many.  

As well as its affordability, 9ct gold is stronger and more durable than purer gold options. Pure gold, or 24ct gold, is very soft and not deemed suitable for jewellery. Greater durability is achieved by mixing pure gold with other metals to form an alloy. The presence of these other metals ensures that your 9ct gold earrings, rings, necklaces, or bracelets are less prone to damage, deformation, or oxidisation, making them the perfect option to become a part of your everyday dressing ritual.

Care and Maintenance  

Although 9ct gold jewellery is stronger and more durable, adequate care is essential in order to preserve its beauty and shine so that it lasts you a lifetime. To keep your NJO pieces looking their best, follow these simple guidelines: 

  • Always remove your 9ct gold jewellery before exercising, swimming or showering 
  • Apply perfumes, creams, fake tan and hair care products before wearing your pieces  
  • Avoid exposing your 9ct gold jewellery to harsh chemicals, including household cleaning agents or chlorine 
  • To prevent damage and breakages, remove your jewellery before bed 
  • To clean your 9ct gold jewellery, polish gently with a jewellery cloth. To remove dirt or residue use a very soft brush and warm soapy water to clean your pieces 
  • Store all your jewellery in a safe, dry place when not worn to protect them from elements of daily exposure
