About Sergio Lub Bracelet Metals
- All Sergio Lub bracelet 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.
- Sergio Lub bracelet's red metal is 99.99% Pure Copper, lead free, the purest available. Copper is one of the friendliest elements as it combines with many others. To find copper this pure in nature is more difficult than finding
pure gold.
- Sergio Lub bracelet yellow metal is Jeweler's Brass, an alloy of 85% pure copper and 15% pure zinc, both essential minerals worn since prehistoric times by many non-related cultures around the world. Science has already proven that metals such as copper are absorbed through the skin, so besides their beauty, our bracelets can also be considered a time-release source of essential minerals.
Machine Made vs. Hand Made
A stamping machine applies many tons of pressure on a sheet of copper to stamp a desired shape, intimately deforming the microscopic crystal lattice of the metal, making it rigid and brittle, 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 may look alike without a microscope, but it feels much different. Please adjust our bracelets on your wrist. Feel the difference for yourself!
