Extraordinary, enchanting and seductive: The solitaire ring The One perfectly accentuates the diamond. Our The One engagement ring develops its special look by a combination of the curved surface of the ring band and the clear, contrasting lines that form the almost free-standing frame. The gorgeous combination of the different shapes makes the diamond raise above the ring band, where it shines bright and sparkling.

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.

Advice for free engraving 

For all the romantics, our free engraving is a great way to dedicate a message to your beloved that will accompany them everywhere.

engraving example – font: Arial

Trend alert: Engraving coordinates

Engraving your first names, with or without date, or a nickname, which often only the partner knows are the most popular engravings.Poetic phrases such as "Forever mine, forever thine, forever ours" or funny things such as "Please say YES!" are often engraved.

engraving example – font: Times

Trend: Engraving cooridnates

We highly recommend engraving the geographical coordinates of your first date. Or your first kiss or the place where you are proposing. The jewellery museum in Pforzheim for example, has the GPS coordinates 48°53'9.622''N 8°41'50.337''E. 

engraving example – cursive handwriting

Free engraving after you propose too!

If you want to propose first, that's no problem. We also engrave your piece of jewellery afterwards free of charge. We also take care of the shipping and return for you!
