ROSE QUARTZ  SPHERES 
The crystal of unconditional love. Brings gentle, soft feelings of self-love. Especially helpful for crown and heart chakras. Its calming energy helps all chakras bringing love, peace and harmony and uniting with the divine.  
Rose quartz is especially powerful when worn close to the heart, as it is believed  quartz wards off negativity, and when carried on your person, helps to replace with positive, returning the wearer to that place of pure love and balance.  
That said, you should never use a crystal to replace the advice and treatment of a qualified healthcare professional.
Spheres measure from 4cm to 4.5cm with stand. 
Chakra:  Heart
