The cool thing about these earrings is that they are in very close proximity to your nose- therefore when you apply your oils to the lava rocks, you can really take advantage of the effects throughout the entire day.  
 
This is the 4th Chakra, or the Heart Chakra.  Compassion, love, kindness stem from this Chakra.  
 
The stone here is Green Aventurine, which is a very positive stone and encourages optimism!  
 
Get one to match a chakra bracelet, or buy all 7 for each of the chakras, and base what you daily wear on the chakra you need to work on!  The lava rock bracelet and earrings make a fantastic gift!
