Our Metals, Care & Guarantee

Copper: Our red metal is Pure Copper. It is free of lead, mercury or other contaminants that are common in industrial grade copper wires. Copper is one of the friendliest elements as it combines with many others. To find copper this pure in nature is far more difficult than finding pure gold. Science has already proven that copper is essential for our health and is absorbed through the skin, so besides their beauty, our bracelets can also be considered a time-release source of an essential mineral. For more information see Copper Benefits.

Brass: Our yellow metal is Jeweler's Brass, also known as new gold because of its color and for not tarnishing with water. Jewelers brass is an alloy of 85% pure copper and pure zinc, both essential minerals, meaning that our bodies must have them in order to remain healthy. Brass and copper have been worn by many different cultures since prehistoric times.

Silver: Our white metal is German Silver, an alloy of 65% copper plus zinc, nickel and silver often used in making white gold. German silver is harder than sterling silver, it got its name from being used first in the German Kaisers silverware. In a few designs, like in Seven Metals or Sterling in Copper, we also use Sterling Silver (92.5% silver plus copper).


Easy Care: Our bracelets are made to be worn at all times and everywhere. We finish them with a thin layer of organic lacquer meant to wear off unnoticeably with use. If you wish to have immediate metal contact, simply wipe the inside of a bracelet with nail polish remover. All the metals we use are solid, with no platting to wear off, therefore any scratch or blemish can be easily removed with a polishing cloth, brass polish, or by rubbing with a lemon rind and ashes. The easiest way to keep our bracelets clean is by taking showers with them on. With this minimal care they should age gracefully with you and last for generations.

Guaranteed Craftsmanship: If you discover a craftsmanship defect in your new bracelet, please bring it to any of our stores within 3 months of purchasing it, for a courteous free replacement. To find your closest retailer please use: Find a Retailer. If you do not have a nearby store honoring our guarantee, or the store owner believes that the problem you are having is not due to our craftsmanship, you may then appeal directly to us by sending the troubled piece, your return address and a $10 check for shipping & handling to: Sergio Lub Returns 3800 Vista Oaks Drive, Martinez, CA 94553 USA.

Please notice that our guarantee covers our workmanship and not the blemishes caused by improper use such as abrasion, trauma, repeat bending or exposure to harsh chemicals. In addition, the copper in our bracelets is meant to eventually wear out after extended use, its useful life varies according to the wearers rate of copper absorption and the weight of the original piece. The breakage of a worn out bracelet is not covered by our guarantee but you can prevent this problem by replacing a tired bracelet after a few years of active duty and saving it to wear at special occasions.

Our Techniques: Annealing & Custom Fitting

All our designs are handcrafted the old fashioned way, starting from solid metal wires. We use no plating, no casting and no machine stamping, all industrial techniques that save time, but compromise quality

Annealing: Is the process of heat treating our metals to relax their crystal structure so they can maintain their malleability. Our wires harden as we braid and shape them, some complex patterns like our Sage Bundle, are annealed several times in order to have a finished bracelet that is easily adjustable and therefore fits comfortably, with optimum metal-skin contact.

A stamping machine applies many tons of pressure on a piece of copper to stamp a desired shape, intimately deforming the microscopic crystal lattice of the metal making it rigid and more rock like. A craftsperson making the same pattern by hand will gradually work the copper to its final shape, taking the time to heat the metal repeatedly so the vibrating molecules can realign themselves and relieve the stress produced by the changes made. This carefully executed heating process is called annealing. The final result of a handmade versus a machine made bracelet may look alike without a microscope, but it feels much different. Please adjust our bracelets on your wrist to feel the difference for yourself.

Custom Fitting: The time consuming annealing process is invisible to the eye but we do it to allow each bracelet to be easily adjusted to fit comfortably and have good copper-skin contact. A bracelet needs custom fitting the first time you try it on, to do so please follow these steps:

  1. Apply one end of the bracelet on the soft underside of your wrist, about 2 from your hand.
  2. Roll the other end on. This is the best way to get your cuff bracelets in & out.
  3. Slide the bracelet over the wrist bone toward your hand.
  4. Close the bracelet until it feels right by hugging it between your thumb and index fingers.

The gap between the ends of your bracelet should be around 1 (between 0.75 & 1.25). If the gap is larger choose a larger size, and smaller if the gap is smaller. See more about finding your size. A bracelet that is your size will allow you to roll in and out (steps 1 & 2) without further bending. Our jewelry is made to last for generations but, if you choose a bracelet size too large for you and if you remove it often, the repeat bending may fatigue the metals and shorten their life.

Our Techniques: Married Metals

Married Metals: A technique of soldering several metals in a piece of jewelry. It requires much skill knowing how to read the torch flame and the different temperatures of each metal from their glow, so they will all be receptive to the silver solder at the same time. Married metals was brought to America by the Spanish Conquistadores and it has been preserved through the centuries in the mountain town of Taxco, Mexico where they call it Metales Casados. Every piece you see involving multimetals indicates a handcrafted product, this is because no mass produced process has been found yet to replace the care and skill of a jeweler. Some crude attempts have been made by selectively platting cast pieces, they are easy to identify since the added colors fade easily with wear.

Preserving Cultural Traditions

Sergio has traveled through every continent learning his craft. From the Andes to the Himalayas, he met master craftsmen who taught him ancient metal working techniques and their deep beliefs of wearing metals for health and vitality. An important part of our company mission is to preserve these valuable traditions by incorporating them into his designs.

Back in 1984 - while visiting a master Tibetan jeweler near Katmandu, Nepal - Sergio noticed a beautiful intricate bracelet with a double silver spiral being worn by his old teacher. The master noticed Sergios interest and taught him how to make it along with its meaning. "During deep meditation, if I feel lost while exploring, I just follow the cord back to myself, he said through our interpreter. In this old Tibetan design the double spiral represents the umbilical cord connecting body and soul. Those seeking deeper levels of awareness have traditionally worn it.

Sergio incorporated this technique into his designs, like in Nepalese Cord, Lifes Spiral and Sherpas Rope. Fifteen years later, in 1999, Sergio took some of these designs back to the Himalayas when he had the great honor to work for a week with His Holiness the 14th Dalai Lama at his home in Dharamsala, India. At the farewell encounter Sergio gave the Dalai Lama one of his Tibetan inspired designs. Afterwards, an elder rinpoche that witnessed the offering approached Sergio to ask how he had learned a technique that they thought it was lost. Sergio told him about his Tibetan teacher in Katmandu to which the elder replied with moist eyes, "I am glad to hear that some of our master craftsmen made it safely to Nepal, the mountain passes are much higher to cross to India and none of our senior jewelers made it here. Then he timidly asked, Would you please show this technique to our jewelers?

Sergio readily agreed and before leaving he passed along the technique to two talented young Tibetan jewelers. Later he reflected in his travel diary, As I explained the design and its purpose to identify those pursuing higher awareness, I myself became conscious of how intimately interconnected we all are and how each of us, through our everyday actions, can help preserve this peaceful culture."
