All About 9kt Gold Jewellery
When it comes to jewellery, there are lots of questions and queries that come up with our MoMuse customers. One of the most common questions is about the material your jewellery is made from – 9kt Gold, 18kt Gold, Gold Filled, Sterling Silver – the list goes on!
One of our favourite materials to craft jewellery with is 9kt Gold, known for its beautiful warm colour, wearability, as well as its approachable price-point.

Here are some of the main facts on 9kt Gold:
What exactly is 9kt Gold?
9kt, or 'Nine Karat Gold' means the piece contains 37.5% pure gold mixed with 62.5% other metals (like silver, copper, or zinc) for extra strength. The '9' stands for 9 parts pure gold out of a total of 24 parts. Genuine 9kt Gold jewellery is often stamped with a 375 hallmark, which represents that 37.5% purity percentage.
How does 9kt compare to 18kt Gold?
The main difference is gold content! 9kt is 37.5% gold, while 18kt is 75% gold. Because of this, there is a slight difference in colour – 9kt gold appears paler than 18kt gold. The added metals in 9kt Gold help with durability and wearability. Because of the higher percentage of gold content, 18kt Gold is more expensive than 9kt Gold.
What are the benefits of choosing 9kt Gold?
9kt gold jewellery is a great choice for its affordability, wearability, and practicality. It offers genuine gold at a lower price than 18kt, while its higher proportion of other metals makes it more resistant to everyday wear, making it ideal for jewellery you wear regularly.
What should I consider when choosing 9kt vs 18kt Gold?
When choosing between 9kt and 18kt gold, consider your skin sensitivity, how often you’ll wear the jewellery, and the colour you prefer. If you have sensitive skin, 18kt gold may be a better choice as it contains a higher percentage of pure gold and fewer alloy metals that can sometimes cause irritation. For jewellery you’ll wear every day, 9kt is a great option with approachable pricing all the while closely matching the look and feel of 18kt Gold.
How should I care for my 9kt Gold jewellery?
A great question! Caring for your jewellery can considerably prolong its lifespan and lustre. To keep your 9kt gold jewellery looking its best, avoid exposing it to harsh chemicals, perfumes, lotions, and chlorine, as these can affect the metal over time. Remove your jewellery before showering, swimming, exercising, or doing household chores, and gently clean it with warm water, mild soap, (always dry properly after) and a soft polishing cloth. At MoMuse, we provide a complimentary polishing cloth with all 9kt and 18kt Gold pieces.
How should I store 9kt Gold jewellery?
Storage is equally important as cleaning. When you're not wearing necklaces or bracelets, be sure to close the clasp in order to avoid tangling which can cause unnecessary stress and damage to the chain and clasp. Hang your jewellery when and where possible, or store in an appropriate case with soft lining. Always avoid keeping your 9kt jewellery in warm or humid places!
