Gold Guide

Two important things to consider when you are looking into purchasing a piece of gold jewellery are the carat and the colour. Both will have an impact on the look and feel of your precious piece so it is a good idea to be aware of the key facts.

Carat is more commonly abbreviated to kt or k, and is a measurement of the proportion of pure gold mixed with another metal alloy, meaning that if the gold purity is high then the value will be too. For example, 18kt gold jewellery will always be worth more than a 14kt piece and this does not change whether you are choosing between yellow, rose or white gold.

Yellow Gold

Yellow gold is considered a classic and traditional choice for jewellery. It is suggested that for those wishing to wear their jewellery on an everyday basis to choose a lower carat as the gold purity is lower, making it a more robust option.

How is it created?

Yellow gold is created combining both pure gold with alloy metals such as zinc and copper. It is important to remember that the higher the carat, the more yellow in which the gold will appear.
This is a desirable characteristic of high carat gold but it is important to bear in mind that it will be softer and more prone to damage.

White Gold

Incredibly elegant and contemporary, white gold is a great choice for those wishing to wear with silver jewellery, as the shades complement each other. It also proves a wonderful setting for coloured stones due to the versatile tone of the metal.

How is it created?

White gold is never completely white, rather an off-white or cream shade which is created by mixing pure gold with a white metal such as silver, magnesium or palladium. Although white gold can be available in a variety of carats, 9kt is most commonly used to ensure durable pieces are made and can be worn every day.

White Gold is essentially Yellow Gold that has been mixed with other metal to whiten it, but it does not become completely white, it remains off white or cream white. It is often plated with rhodium, which in time wears off so regular re-plating is often required to maintain its whiteness.

Rose Gold

Fashionable and elegant, rose gold has been used to create jewellery since the 1920s, however, has risen to popularity more recently possibly due to its stunning and surprisingly versatile blush hue.

How is it created?

This unique gold colour is created by mixing pure gold with copper alloy to form the signature blush tone, this hardier material is perfect for everyday wear. A higher carat will create a pinker tone, whereas rose gold created using more copper will have a redder appearance. It is important to bear in mind that rose gold can affect people with copper allergies, if you have sensitive skin it is a good idea to choose a higher carat of gold.


Both durable and versatile, platinum is a great option for those looking for a hard-wearing metal which oozes stylish simplicity. This precious metal is naturally white in colour making it a wonderful option for pairing with any type of gemstone.

How is it created?

Platinum, unlike other metals, does not need to be mixed with a large amount of other substances, in most cases, it is available in an almost pure form - 95%. Due it’s near pure form, platinum is less prone to scratching and will retain its brilliance and colour over time. This also makes it the ideal choice for those with allergies or sensitive skin due to it being a hypoallergenic metal.
