When we started this project we wanted to help people approach plant care as a form of self care.  In order to help the people help their plants we added healing crystals to each of our planters. And who doesn't like  a good plant tchotchke, right? 
We are happy to pick for you, or please don't hesitate to contact us if you have something special in mind.  We've put a list of common crystals in this price range we use below but we are always happy to hunt for the perfect crystals and accommodate your needs.
