The Style: This is a classic example of Brutalist design (popular in the 1960s and 70s). It’s characterized by the "bark" or "molten" texture on the metal, which was often achieved through a process called reticulation—heating the silver just until the surface begins to melt and ripple. The Stone: The center stone is an Orbicular Jasper (frequently called Ocean Jasper). These are prized for their "eyes" or circular patterns. The mossy greens and earthy oranges in your stone are very high quality and typical of deposits found in Madagascar.
