Vintage 70s Chunky Solid Silver & Purple Stone Ring K

Vintage 1970s chunky solid silver and purple stone ring. Nicely faceted purple stone, probably glass or synthetic amethyst. The silver is covered in bark effect engraving. Stamped for silver inside the band and at the back of the setting. Size K to L but with wider rings it's better to go for a slightly larger ring, so I am saying this is a K. 10g in weight and the setting is 2.3cm by 1.4cm. The ring is in excellent vintage condition and has obviously not been worn very much as there is no thinning to the band and the engraving is still well defined. Fabulous ring! Box included.
