Sergio Lub Jewelry is a brand that handcrafts each of their bracelets in their Northern California Studios. Their bracelets are designed to be adjustable and worn continuously, aging gracefully over the years. Many of their bracelets feature complex combinations of separate metal pieces, and to ensure durability, they use silver solder to carefully join the metals together.

The primary materials used in their jewelry include pure copper, jewelers' brass, and German silver. They offer bracelets in different sizes to cater to various wrist diameters. Custom fitting is also available, and their bracelets can be easily adjusted to fit each unique wrist.

Sergio Lub Jewelry is known for their love of copper, as it is an essential trace mineral that has beneficial properties for the human body. Their magnetic bracelets contain powerful rare earth magnets carefully positioned over pressure points in the wrist to enhance circulation and provide potential health benefits. To maintain the beauty of their bracelets, they provide care and maintenance instructions, and their solid metal bracelets can be easily cleaned and restored to their original shine
