Quartz is the most common mineral on Earth. It has a hard glassy surface and occurs in many shapes and colors. Clear quartz is found in masses, in clusters or as points, which are pieces of clusters. Quartz generates an electrical charge and has many scientific, industrial and metaphysical uses. This tumbled variety is smooth and translucent, giving it a very beautiful appearance.
Great for science projects or classroom collection.
Note: Please be aware that this is a natural mineral and as such each piece is one of a kind! The one you receive may not be exactly the same as the one pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights.
