    We individually handcraft each of our bracelets in our Northern California Studios.
    Our bracelets are adjustable and designed to be worn continuously, aging gracefully as they last for years.  

    Many of our bracelets have complex combinations of separate metal pieces. To ensure our designs withstand the stress and strain of constant wear, we use silver solder to carefully join the metals together. Soldering several metals together into the same piece of jewelry requires delicate precision, and with practice one learns how to understand the different temperatures of each metal, by reading their glow as they are heated with a torch.


    Our Primary Materials Include:

    Pure Copper – The red/pink-ish metal found in many of our bracelets.

    Jewelers’ Brass – The golden metal we use is an alloy (mixture of metals) containing approximately 85% pure copper and 15% zinc, another essential trace mineral for the human body.

    German Silver – German Silver is the primary white metal we use. It is an alloy of 65% pure copper mixed with zinc and nickel.


    Bracelet Sizing

    Small - For wrists up to 6" in diameter
    * Common children’s size, & for a petite size wrist…

    edium - For wrists 6" to 7" in diameter
    For most Women, and some Men of medium build...

    arge - For wrists 7" to 8" in diameter 
    * Most common Men’s size, & also for a more voluptuous lady.

    arge - For an 8"+ diameter wrist 

    When you have the bracelet on, there will be a gap between the two metal ends. This gap should be approximately 1” wide… (between .75” & 1.25”)
    - If the gap is wider, you may consider choosing a larger bracelet.
    - If the gap is narrower, than consider choosing a smaller size bracelet.



    Sergio Adjusting Bracelet

    Custom Fitting & Adjusting Your Bracelet



    We take the extra step of annealing our bracelets to ensure their longevity. Although invisible to the eye, this process allows each bracelet to easily adjust to each unique wrist. A properly fitted bracelet will provide reliable and comfortable contact of copper with skin. 

    Since every wrist is unique, each bracelet will need custom fitting the first time you try it on. 

    1. Choose your bracelet size.
    2. Apply one end on the soft underside of your wrist (approx. 2" from your wrist bone), and roll the bracelet on.
      - We call this “The Sweet Spot” (note: It is slightly higher and often wider than your actual wrist, but is softer and more forgiving than your actual ‘bony’ wrist. 
    3. Slide the bracelet down over your wrist bone, and adjust the piece to fit comfortably on your wrist.

    * A bracelet that is your size will allow you to roll on and off (steps 2 & 3) without further bending.


    Is a technique used in metal work, of heat-treating metal in order to relax and realign its crystal structure. Annealing is meant to reduce hardness and increase metal’s flexibility. Since metal tends to harden the more it is worked with, some of our more complex patterns, such as the Sage Bundle, are annealed several times before they find their human wrists.


    We LOVE Copper!

    “Copper is an essential trace mineral, present in all body tissues, which plays a role in the formation of connective tissue, and in the normal functioning of muscles and the immune and nervous system.”  – Dr. Andrew Weil, M.D. (read more)

    “Copper is an essential element for the enzyme that regenerates the cartilage lining our bones and to clean up the radicals destructive to human tissues.” 
    The Copper Bracelet and Arthritis, Dr. Helmar H. A. Dollwet, Professor of Biology, University of Akron, OH

    “Copper, when in contact with the skin, forms chelates with human sweat, and is thus absorbed through the skin.
    Think of a bracelet as a time-release source of copper."
    - Dr. R. Walker, University of Newcastle, Australia.

    “Copper chelates are more effective and less toxic than drugs being used to treat arthritis.”
    - Dr. J. Sorenson, University of Arkansas, USA.

    “Treat inflammation with pulverized copper.”
    - Eber Papyrus, c. 1550 BC 

    “The natural content of copper and zinc in commercially grown produce have been steadily decreasing due to soil depletion. Copper and zinc are essential minerals to sustain human life and they are the main metals in our jewelry.”
    - Sergio Lub


    Each of our magnetic bracelets contains two powerful Rare Earth Magnets; one at each bracelet tip, carefully positioned to be worn over the wrist’s pressure points. Research has shown that magnetic fields influence biological systems and are believed to attract and repel charged particles in the bloodstream increasing circulation, stimulating tissue regeneration and reducing pain. In 1954, Dr. Linus Pauling received a Nobel Prize for his discovery of the magnetic properties of hemoglobin. Pauling found that iron and many electrolytic salts in our blood, circulate bio-magnetically. Therefore, the proximity of a magnetic field may result in an acceleration of circulation, and the transfer of energy to all areas of the body.

    For millennia Chinese doctors have believed that a magnetic field, when next to the body, could markedly increase the wearer’s vital life force, known as ‘Chi’. The observed benefits were found to increase with the magnets’ proximity to acupressure points. We carefully place magnets in our bracelets near two important pressure points of the wrist. 


    Care & Maintenance

    Our bracelets are made to be worn at all times, in nearly all places. To keep your bracelet clean we recommend wearing it in the shower, and when necessary using a simple jeweler’s polishing cloth to restore its shine. With minimal care your bracelet should age gracefully.

    Our bracelets are made of only solid metals, so there is no plating to chip or wear off. Therefore a scratch or blemish can be buffed out with a simple polishing cloth, or by rubbing a lemon juice / baking soda composite.

    If dirt or patina build up, you may enhance cleaning by using a liquid jewelry cleaner on your bracelet, and finish with a jeweler’s cloth to buff your bracelet to a shine. Please note that copper patina is a natural occurring process that varies depending upon exposure to elements. 


    Copper Wear Over Time:

    Since copper may be absorbed through the skin, extended periods of wear may soften the metal. Customers who have worn Sergio Lub Bracelets for years have experienced this. A worn or thinned bracelet is not a fault of our craftsmanship but a testament that customers have worn the metals, and it may be time to upgrade to a new bracelet. Please visit our Store Finder to find a location near you.


    Guaranteed Craftsmanship

    We take pride in our work, and make a quality product. If you notice a craftsmanship defect (such as a sharp edge), please contact us for a replacement.

    Excessive bending will stress any metal, and can cause breakage. Improper and excessive bending is not considered a craftsmanship defect, and is not covered by our craftsmanship guarantee. 


    Magnet Replacement

    If you lose a magnet from one of our bracelets, please contact us and we will send you a free magnet with instructions on how to replace it. It's easy!
