Coming fresh out of the Mamuju region of Indonesia, these botryoidal beauties burst onto the scene and have become a must-have specimen. Previous to these recent discoveries, Indonesia was a relatively obscure locality for collectors and was primarily known for hosting the largest gold mine in the world (something not many of us have the privilege to collect).
Although they’re referred to as grape agate, these crystals are in fact spherical clusters of micro amethyst. The name isn’t altogether incorrect though, as agate is actually a variety of quartz. Meaning they share the same atomic structure of 1 silicone atom and 2 oxygen atoms. The primary difference being that, due to a different geological environment, when agates form the individual crystals grow much smaller and in a tight radial fashion. This is what leads to the color bands and bubbly shapes commonly seen in agate geodes. This growth pattern is also what is responsible for causing the remarkable grape like crystal form you see before you!
