SARAH & SEBASTIAN Chroma 10-karat gold, diamond and opal necklace

SARAH & SEBASTIAN's 'Chroma' necklace is centered with a marbled opal, the signature gem of the label's native Australia. It's hand-cast from gold with a curved crescent-moon pendant and further illuminated with dainty brilliant-cut diamonds. The slender chain and delicate profile make it the ideal everyday piece.
