A distinguished, sculptural masterpiece of Finnish studio modernism, designed in 1976 by master Karl Laine for Sten & Laine (Finnfeelings). The large, asymmetrical pebble-form head highlights a sweeping polished plane bordered by Laine's iconic deep bark-textured outer wall. Resting within an oxidized circular recess in an elevated collet setting is a brilliant, faceted natural rock crystal (clear quartz) radiating crisp icy fire. The open adjustable shank offers comfortable versatility and bears the designer's engraved "KL" monogram signature on the textured side, alongside full Finnish hallmarks on the interior: the Sten & Laine maker's mark, 925 purity mark, national crown assay mark, "Y7" year code (1976), and "FINLAND".
