These octahedrons of magnetite (or loadstone) have been selected for their fine crystalline formation and for their small size.

These stones can be used in rituals connected to the third karma, magnetism, or more generally, as an offering to protectors. One can also mix them with rice and other stones for a mandala offering.

The edges are, on average, about 10 mm.

These stones are natural. Even though this type of magnetite doesn't release a strong magnetic field, it is still not recommended for those wearing a pacemaker.
