White gold jewellery in Australia is extremely popular for a number of reasons. Firstly, it looks great! Not only that, it is an especially strong material, therefore making it favoured for engagement rings. In fact, white gold is used in almost every type of jewellery. So, what exactly is white gold? Read on to find out more! What is white gold? White gold is a mixture of pure gold and alloy metals such as palladium and silver. This isn’t a way of cheapening the product, it’s merely a practical necessity. Gold in its purest form is too soft for jewellery, as it would bend out of shape easily. Therefore, the gold is mixed with stronger materials for extra durability. In the case of white gold, the mixture is usually palladium and silver, giving it that white or silvery appearance. The same occurs in all types of gold jewellery, but the type of alloy depends on the desired colour. For example, rose gold is a mixture of different alloys. White gold and rhodium A rhodium coating is used on white gold jewellery in Australia. This is actually quite a precious metal, from the same family as platinum. Not only does rhodium add further strength, but it also gives white gold a certain surface sheen. While the alloys discussed earlier will tint the metal a silvery/white colour, the rhodium caps it off with added colour. Caring for your white gold jewellery in Australia While rhodium gives your white gold jewellery a great appearance, it does tend to wear off over time. Essentially, the rhodium starts to wear off and reveal the more yellow gold underneath. It’s perfectly normal, but the life span of your rhodium coating depends on a number of factors. The pH levels of your skin or exposure to elements can affect the lifespan. Every 1-3 years, you may need to have your white gold jewellery re-coated, but don’t worry – it’s not a super expensive exercise. How much of white gold is pure gold? ‘Karats’ are the white gold jewellery measurement in Australia. This refers to the amount of pure metal in each piece of jewellery. For example, a 9 karat white gold ring will be 37.5% pure gold. Likewise, 18 karats is 75% pure gold. At Catanach’s Jewellers, we’re masters of our craft.
