Style specifics: Modernistic Seventies

Period: ca. 1975

Extra information: Although not marked by a master mark – (unless the mark AMO (?) is a master mark) we think this style has great resemblance with the style of Kutchinsky

Diamond(s): Eight brilliant-cut diamonds with an estimated weight of 0.40ct. (colour and clarity: H/J, vs/si).

– All diamond weights, colour grades and clarity are approximate since stones are not removed from their mounts to preserve the integrity of the setting.
