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.  
 
These earrings celebrate the 2nd Chakra or the Sacral Chakra where sexual pleasure is rooted.  It is located just below the naval.  Its color is orange.
 
I used a orange dyed Quartz in this piece.  Quartz is a classic stone, not only used metaphysically, but in many timepieces, tools, etc.  With Quartz, you can feel an overall healing experience as well as using its capabilities to "program" memories as well as intentions.  
 
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!
