The Alter gold ring is made entirely of titanium. It has a diameter of 6mm and a faceted finish on the outside. Why did we choose titanium? It is light as a feather. It is super strong. It is an exclusive material that is also used in racing cars, motor boats and aerospace. The ring has a comfortable fit on the inside and is very comfortable to wear. Thanks to the lightweight titanium, you can wear this ring day in, day out without any problems. The model name 'Alter' is derived from Latin and means 'other' or 'other than'. This is certainly the case: this ring is different in the most positive way! Thickness : 6mm.
