Gemini bracelets are made of natural stones. The brand was founded in 2013 by the twin brothers. Gemini is currently the largest manufacturer of natural stone bracelets in Europe. The bracelets are handmade in Belgium, but they are made of stones from all over the world, including Mexico, Eastern Europe and Asia. Each of the stones used in bracelets has a different meaning and property. For example, sodalite protects against negative energy, howlite soothes nerves and stress, and tiger’s eye helps to achieve one’s goals.
