Mexico's Guillermo Arregui designs a luminous choker of arresting beauty. It is cast of sterling silver and centered by a glowing amber gem. Crowned with an iridescent pearl and peridot, the pendant glistens with tumbaga, a gold and copper alloy developed since pre-Hispanic times.

.925 Sterling silver

When used in jewelry, amber beads can include a stunning arrangement of tones and hues. Natural amber ranges from yellow to deep orange. It may sometimes even have a green cast to it, as well as opaque swirls within. Because amber is the preserved resin of prehistoric trees that grew millions of years ago, it sometimes has tiny inclusions of plants and insects -- making it highly prized.
