Tembaga Moss Agate, sourced from Indonesia (specifically Java or Sumatra). The word tembaga translates to "copper" in Indonesian, referencing the warm reddish-brown, rust, and golden-ochre mineral inclusions suspended in translucent quartz and chalcedony.
Some seriously yummy stuff already! The bubbly, grape-like clusters along the raw right edge are known as botryoidal chalcedony. These globular shapes form naturally inside open pockets (vugs) when silica-rich fluids cool and deposit around tiny mineral nuclei.
