These are smallish standing clear Quartz points/pillars. I can pendulum which one is right for you if you wish. 

They are approx 3.5-5.5cm tall and 2-2.5 wide. 

Clear Quartz is a powerful healing crystal that cleanses and amplify’s energies. It also absorbs, stores, releases and regulates energy. It’s a master healer and is a must have for home and your healing kit.
