This piece is a silver ring with a square, textured plate – a modernist or Brutalist-style piece distinguished by its hammered or reticulated surface, which creates a relief effect and unique reflections of light. 

Design details and usual materials: 

Material: The vast majority of these pieces are made from 925 sterling silver. 

Texture: The rough surface is usually created through hand hammering, thermal reticulation of the metal or engravings that imitate organic elements of nature. 

Structure: The geometric plate (square or rectangular) is soldered onto a ring shank, which can be fixed or adjustable to fit different ring sizes.
