Gold - the classic metal. Gold is one of the oldest metals if you look at how it has been used for a very long time. There is actually evidence that gold began to break down already 7,000 BC, perhaps this is a metal for those who like classic things. A ring made of yellow gold is not entirely made of just the metal gold as it is basically very soft. Thereby, it alloys, mixes gold with other metals that make it more durable. However, yellow gold is still the softest metal we have on our rings, so if you are a person who is very active, we would recommend you to choose another metal.
