Vintage alexandra essex 18kt yellow gold and chrysoprase bead hexagonal necklace

Santa Barbara-based Alexandra Essex founded her eponymous jewelry label in 2006. Dedicated to the finest craftsmanship and attention to detail, she creates innovative, one-of-a-kind designs that showcase the beauty of rare gemstones. In the case of this necklace, chrysoprase—a rare variety of chalcedony with a minty, apple-green hue—is the gemstone in the spotlight. Taking shape here as hexagonal beads, this stone forms a beautiful contrast against the intricately engraved 18-karat yellow gold detailing.
