Retained in original presentation box from 'Lester Berg Jeweler, 1416 Third Avenue, Seattle, Wash.' suggesting a Pacific Northwest regional origin and continuous single-family or collector ownership.
Art Historical Significance
Representative of American regional luxury retail during the mid-20th century prosperity. It reflects the post-war trend for 'cocktail jewelry' which used dramatic shapes and dark stones as affordable alternatives to high-jewelry diamonds/sapphires.

Minor surface wear on the band (shank); slight yellowing of the silk interior and plastic shell of the presentation box; potential oxidation of the metal.

Professional ultrasonic cleaning of the setting (if metal is gold); avoid harsh chemicals; store in the provided original acid-free box environment away from direct sunlight.
