What is the difference between 18k and 9k gold?

The classic choice and the very definition of fine jewellery is 18 karat gold, which holds more pure gold than 9 karat. 18k gold is a given choice for diamond rings as it is stronger and doesn't tarnish - a more durable choice and a heirloom to be passed on to future generations.

We offer demi-fine 9 karat yellow gold within our plain bands only, as 9k gold holds a higher proportion of other metals (62.5%), is softer and more likely to slightly tarnish over time. Despite being less durable than 18k gold, 9k gold is an excellent choice if you wish to keep costs down while keeping a premium feel.
