Gold is a naturally occurring metal with a warm, glowing finish when polished, and remains the most popular choice for engagement rings due to its natural beauty and hard-wearing strength.

Pure 24k gold is naturally a soft material, and considered too soft to create jewellery with, so it is mixed with small amounts of other metals to create an alloy.

As well as increasing the durability of the gold, adding alloys can also change the colour of the gold to produce rose or white gold, for example.

18k yellow gold is made up of 75% pure gold, and 25% alloy, which would usually include silver and copper.

18k rose gold is made up of 75% pure gold, 22.2% copper, and 9.2% silver.

18k white gold is made up of 75% pure gold and 25% palladium or platinum.
