Precious Metals Guide
When it comes to selecting the precious metal for your jewellery, everybody has a unique preference. We offer a range of precious metals for you to decide between, including platinum, rose gold, white gold and yellow gold.

Recycled Gold
Gold mining has a terrible history of human rights abuses, unethical labour practices and destructive environmental impacts. To produce enough gold for a single ring, over 20 tons of ore must be moved - resulting in extreme environmental devastation. Mining destroys the natural environment, creates water pollution and often intrudes upon indigenous people’s rights.
At Cullen Jewellery, we are committed to providing ethical, environmentally-conscious fine jewellery to our customers. For this reason, we exclusively use recycled gold for all of our ring settings.
What is Recycled Gold?
Put simply, recycled gold is gold that has been melted down from already existing gold products such as old jewellery, unused metals and waste. Since gold is naturally renewable, it can be melted and recycled over and over without ever losing its purity or value over time. To mine for new gold, natural forests and habitats must be cut down - recycled gold breaks this destructive cycle by re-using existing gold!
What’s the Difference Between 9K, 14K and 18K Gold?
You may have heard of the term “24 carat gold”. This is the name given to 100% pure gold. Beautiful, yet very soft and malleable, it is impractical for everyday wear. To make it stronger and more suitable for jewellery, gold must be mixed with other metals, called “alloys”. This can be metals such as silver, tin, nickel, zinc and palladium. When referring to carats (or karats), the number of carats in gold is a measurement of how much of the alloy (out of 24 parts) is made of pure gold. For example, in 9k gold, 9 parts out of 24 are made of pure gold and in 18k gold, 18 out of 24 parts are made of pure gold. The other parts are a blend of different metals used to reinforce the strength of the jewellery.
As you can guess, the less pure gold in the mix, the less expensive it is. Selecting a lower carat gold can be helpful for those working within a tight budget but it is important to note that 9k and 14k gold may have a paler colour due to the lower gold percentage.
Did you know?
Your gold ring will usually have a three digit number stamped on the inside of the band. This signifies the purity of the gold. Since 9k gold is 9/24 pure gold, and this fraction in percentage form is 37.5%, the number “375” will be stamped to the ring. Similarly, 18k gold will have a 750 stamp to represent the 75% (or 18/24) pure gold.
