Labradorite cufflinks by Turun Hopea, Finland 1982

This stylish pair of 1980s cufflinks from Finland are set with labradorite, a mineral that displays an irridescent optical effect. The labradorite looks almost black at some angles but when it catches the light it displays a wide range of subtle colours. 

They are in excellent used condition and have a full set of Finnish hallmarks for continental 830S silver. 

Turun Hopea Oy is a Finnish silversmithy.
