Metal Guidance

Precious metals have been used for centuries to craft exquisite pieces of jewellery.  Choosing your metal plays an important part when making your purchase by affecting the durability, the appearance and cost of your perfect piece.

The traditional metals used to make jewellery are platinum, gold and silver. In more recent years palladium has become increasingly popular.


Platinum is one of the most durable and dense metals, making it a popular choice to make jewellery with.  It is naturally white in colour with a sheen that will never fade. It complements diamonds perfectly.  Its rarity makes it more costly than gold, but its strength ensures that it stands the test of time.

At Diamond Aurora all of our platinum is 95% pure (5% palladium) and every piece has a British hallmark.  Its high levels of purity make it naturally hypoallergenic - perfect for those with sensitive skin.

Though it is the strongest of the precious metals, platinum can mark or incur scratches so it is important to look after your jewellery carefully.  To clean your treasured platinum pieces soak them in warm, soapy water and gently scrub them with a soft bristled brush.


Gold, the most malleable of the precious metals, is naturally yellow in colour.  In its purest form it is too soft for everyday wear.  To give it strength and durability gold is mixed with different alloys such as palladium, silver, zinc, or copper.  It is available in a number of purities which is described by the term 'carat.' The legal standards recognised in the UK are 9ct (375), 14ct (585), 18ct (750) and 22ct (916). The higher the purity of gold, the more expensive it is.

At Diamond Aurora we craft our jewellery predominantly in 18ct gold which has a purity of 75%. It is mixed with different alloys to make it durable for everyday wear.  All of our pieces made from 18ct or 9ct gold are stamped or lasered with a standard British hallmark.
The colour of gold is determined by the type and the percentage of the metal alloys when they are combined.

Yellow Gold is warm and rich in colour and has been treasured for centuries.  The alloys traditionally mixed with pure gold are silver, zinc and copper.  The higher the percentage of gold, the more yellow it is in colour.

White gold is made by mixing pure gold with palladium or silver.  In its natural state white gold can appear to have a slightly yellowish tone.  To make it shiny and silver in colour it is plated with a thick layer of Rhodium.  Rhodium plating can wear away over time but it can easily be re-plated to restore your jewellery to its bright white colour.

Rose gold is increasingly popular.  Its pretty pink tones are created by combining copper with pure gold.  Its soft warm colour looks particularly beautiful when partnered with the other colours of gold.

As gold is a soft metal it can incur abrasions during daily wear. To prolong the lustre, we advise you to store your gold pieces in individual soft cloth bags or the original box it came in.  Although gold does not tarnish or rust, it can react to certain chemicals such as chlorine or certain cleaning products. We recommend that you remove your jewellery before using these products to protect your treasured pieces.  To clean gold jewellery soak it in warm soapy water (detergent free) and gently brush it with a soft bristled brush such as a toothbrush. 


As part of the platinum family, palladium is also naturally silver in colour and has hypoallergenic qualities.  It is a lighter choice than platinum and offers a more affordable option.  It is extremely durable and provides a less costly option for wedding bands, particularly for men with larger finger sizes. 

At Diamond Aurora we sell only palladium with a purity of 95% (5% Platinum). All of our pieces are stamped or lasered with a standard British hallmark.

To care for your palladium jewellery, soak your items in a solution of soapy warm water and brush with a soft bristled brush. Store them separately, each in its original box or a soft cloth bag, to ensure that it is protected when not being worn.
