These beauties are a combination of two glorious minerals (Quartz and Calcite) in half-geode form! Quartz, the second most common mineral in the Earth’s crust, possesses a very rare property called piezoelectricity. This means that when Quartz is compressed, it produces an electrical current and conversely will begin to expand/contract (vibrate) when electricity is applied to it. This incredible phenomenon is why quartz crystals are used in wristwatches. Calcite is a rather common mineral that ranges in shape, texture, size, and clarity, from being almost gem-like lustrous to more rock like and dusty! 


These particular specimens are B and C grade and contain minor imperfections, but are nonetheless beautiful and unique in their own right.
