A fantastical flight of fancy by Carrera y Carrera, the designer necklace is crafted of luminous 22 karat yellow gold, depicting a mermaid and swordfish splashing through the surf. Composed as a bar-style necklace of 18k gold with a pair of diamond accents, their highly detailed creations are coveted by collectors. All collections are still made by hand in Spain since the 1800s.
