Very distinctive ring with a large oval green stone, featuring subtle shades and veins on its surface. 

The stone is set in a silver-coloured setting with numerous decorative prongs surrounding it.

The ring band is rather wide and features engraved workmanship on the surface, giving it a handcrafted and ethnic style. 

It is a substantial and eye-catching design, intended to be worn as a statement accessory.

The metal shows a natural patina and some signs of age, also visible in the photographs, which contribute to the vintage character of the piece.

No hallmarks or markings are visible that would allow the metal or stone to be identified with certainty. 

Used, in generally good condition considering its age and normal wear.
