The Gold Standard

Posted by on

I've had several questions recently about gold and it's different carats and colours, so thought I would repost some of the information from my first ever blog post, with a few updates.

Gold is, in it's natural form, spectacularly yellow. It doesn't tarnish with age, as silver and copper do, but comes up out of the ground shining bright. As with most metals, it is combined with others to create alloys with more useful properties. Gold is very soft for a metal, in it's purest form.

I offer many of my stacking rings in either 9ct or 18ct gold. The term carat comes from the greek word, carob. Dealers would use carob seeds when measuring gold, as they had a uniform weight. The amount of gold in an alloy is measured out of 24 parts. 

18ct gold is therefore 18 parts gold to 6 parts other metals, or around 75% pure gold. 9ct gold is around 37.5% gold.

The 9ct golds which most of my stacking rings are pictured in on this site are very soft in colour. As someone who didn't ever think the bright yellow of gold would suit them, I find their softness hugely flattering. They are much warmer than silver, whilst still being gentle in colour.

 Red or rose gold, which is hugely popular at the moment has more copper than the other alloys to give it it's gorgeous red tone. 18ct red gold is very rich, due to the 75% yellow gold. 9ct rose is softer, more delicate in colour. 

White gold is the alloy which differs most between it's 18ct and 9ct versions. 9ct white gold is a soft, warm white, as you would expect of silver with the addition of a yellow gold content. 18ct generally has palladium added, which is a similar alloy to platinum. This means beneath the bright white plating most shops add to white gold the colour is very similar to platinum.

If you have questions regarding the options for any of my rings drop me an email at, I'd love to hear from you.
