Precious metals - the most important criteria 

Yellow gold, white gold and rose gold are available in alloys of 14 carats (58.5% fine gold) and 18 carats (75% fine gold).

All our jewellery is nickel-free! 

White gold (Wg) is a light, white-grey alloy of gold, palladium, and silver. It is particularly popular for engagement rings.

Valuable silver 925/- (sterling silver, Ag) consists of 92.5% pure silver. 7.5% is made up of other metals, such as copper.

Rose gold (Rg) is a pink alloy of fine gold and copper. The higher the copper content, the redder the colour.

Yellow gold (Gg) used for jewellery is an alloy of gold, silver and copper. It is the most popular gold colour in the world.

Platinum 950/- (Pt) is a rare and expensive precious metal. Platinum has a high density, it is particularly durable and robust.

14 and 18 carat alloys - durable & stable

Only the addition of silver and copper (among others) to pure but very soft fine gold makes gold alloys durable and resistant.

The colour also changes from golden yellow to pink to silver white according to the mixing ratio.

How much fine gold is included? 

Alloys with a fineness of around 14 carats (or 58.5% pure gold) have the highest strength and hardness. At 18 carats it is already 75.5% fine gold. Alloys with a higher proportion of fine gold are extremely susceptible to scratches and mechanical stress.

You'll only receive nickel-free jewellery - perfect for allergy sufferers and anyone with sensitive skin.
