What are the jewelry made of?

All our jewelry is made of 925 sterling silver, which is the most suitable form of silver for jewelry. 925 is the hallmark for sterling silver, and this hallmark may only be used if one is a member of the Danish Precious Metals Control, which we are.

Our gold-plated jewelry is sterling silver coated with an extra thick layer of 18 karat gold. All our gold-plated jewelry is coated with 2-3 microns of gold, and the color is adjusted to 14k gold. This means that our jewelry offers very good quality for the price.

Our jewelry is marked with Aiu Aio 925S, proving that the jewelry is made of sterling silver and made by us. Our mark is registered with Force Technology, which is the official precious metals control in Denmark.

We continuously test our jewelry to ensure that we provide you with the best quality, so you can always be sure that the materials meet Danish regulations.
