All John Medeiros jewelry comes with a lifelong guarantee and is handmade in the U.S. Each piece of jewelry’s base material is composed of a non-precious lead-free premium alloy with 0.02% silver, and an overlay/finish/plate of Rhodium and 14kt Gold. Rhodium has all the characteristics of platinum plus the extra benefits of being harder, lasting longer, and having a whiter tone. All stones are man-made Cubic Zirconium, indistinguishable to the eye by diamond experts. All earring posts are made of surgical steel.

All John Medeiros works are original designs and contain intricate hand carved detailing. The John Medeiros logo is proudly displayed on each piece.
