As with other precious metals and gemstones, the purity of gold is measured in karats (“k” or “kt”). The number of karats represents the purity of the gold in a particular item. For example, a 24 karat gold piece will be the purest at 99.99% gold or all 24 parts pure gold. Likewise, 18 karat gold has 18 out of 24 parts pure gold. The remaining six parts are made up of other metals (alloys) to harden the gold and brighten or change the colour. For that reason, 24 karat gold is the softest, and 10 karat is the hardest. Our rings are always made of 14 karat gold, so as to provide you with a durable piece of jewellery that will wear beautifully for a lifetime.
