【K9】
The proportion of gold is 37.5%. Gold is particularly popular in the UK. For this reason, it is commonly referred to as Royal Gold or British Gold, and is a romantic gold.
Compared to K18...
It is about 20% lighter and has a large amount of gold, so be careful if you have a metal allergy. Furthermore, if you go to a hot spring or the sea while wearing it, there is a high possibility that the color will change, so be careful when using it on a daily basis. However, it is harder than K18, so it is less likely to get scratched.
【K18】
The proportion of gold is 75%. Gold is the main material used in Japanese jewelry.
Compared to K9...
It has a luxurious feel and high gold content, making it extremely unlikely to cause allergic reactions. In addition, it hardly changes color even in normal daily life and can be used for a long time. You can easily wear it because you don't have to remove it every time you go to a hot spring, the sea, or use detergent (please be careful as it may occasionally discolor). However, since it is softer than K9, it is easily scratched.
