Depending on the depth, pressure, time and regional geology, Chalcedony may grow in Botryoidal form. This happens when the environment has abundant tiny particles that enter the silica gel. The Chalcedony then use these particles as nucleation spots and grow radially around the particles at the same speed, forming spheres. These spheres grow into one another as they get larger and can be seen as small intergrown spheres or bubbly masses. Botryoidal Chalcedony can be white, gray, blue, purple, pink or brown.

Care and handling

Truffle Chalcedony is fairly hard, about 6.5 to 7 on the Mohs scale, but its bumpy surface holds dust and can chip at the edges.

Store it padded to protect its rounded clusters.

Individual experiences with Truffle Chalcedony vary, and its effects are personal. Hold it mindfully, feel its bumpy, earthy surface under your fingers, and let it bring you back to the present moment.
