The Science Of Metals

Decided on your stone but not the band? Metal choice needs careful consideration. Don’t get baffled with complex terminology, learning the basics along with our help will help you to make the right choice in regards to value and aesthetic.

Glowing Yellow Gold

Rose gold and yellow gold engagement rings.

Yellow gold engagement rings are stunning, and gold, due to its scarcity, is highly valued too. Alloyed with other metals, such as copper and silver, it becomes strong and easy to work. 

The amount of pure gold in jewellery is measured in carats . 18-carat gold engagement rings are 18 parts pure gold and 6 parts alloy. Still gold, but tougher and resistant to rust, corrosion and tarnishing, this metal needs no re-coating and retains its beauty with little more than an occasional polish.

Elegant White Gold

A popular alternative to yellow gold and platinum, I often recommend this silver-coloured gold as a contemporary colour choice which can offer you great value for your ring. 

Varying amounts of gold are used in white gold, but the metal alloys (silver and palladium) determine the light colour and add durability. However, white gold engagement rings do need re-plating every 12-18 months.

Romantic Rose Gold

This relative newcomer among gold engagement rings has increased in popularity. The pink hue touches the romantic side of many people, making it a great colour for an engagement ring. Rose gold is, like yellow and white gold, just a mixture of different alloys used to give it its unique colour. Copper is the favoured alloy and the amount used determines the degree of the hue, carat and durability. 

Prestigious Platinum

The most durable and pure of all the metals, platinum is 35 times more rare than gold. It is softer than some lower carat gold and can scratch, but its malleability and resistance to cracking makes it ideal to be used in jewellery. 

Its density and abrasive resistance add to its durability and when polished, due to its molecular structure, it doesn’t lose a layer. Platinum’s white colour is natural so no re-plating is required. At 95% pure, alloyed only with other similar metals, its hypoallergenic qualities are clear.
