Smoky Quartz is such a gentle healer.  It helps to bring about a feeling of peace and calm.  Which can be so helpful during stressful times such as life changes and dealing with emotional issues.  Our pets also deal with emotional problems and often need a little crystal healing to help them through the difficult times as well.  This is a beautiful way to add jewelry to your pet's collar. 
 
This is one of our smaller pendant charms that measures just over 1/4 inches around.  The entire length of the charm is 3/4 inches.  It is made by hand using silver Artisan wire that has a copper inner core. Over time and exposure to moisture, you will see the lovely copper patina showing through. It is suggested you try to wipe the crystal pendant dry if you notice it is wet. 

We've done a lot of field testing with our pet healing crystal line and when you combine the crystal sitting next to metal ID charms and you have a very active pet? The crystal can be damaged due to the banging against the other parts of the collar.  So we suggest you place the charm carefully. 
 
The crystal will come ready to attach to your pet's collar with a strong metal ring. The purple collar in the photos is an example only to show you what it would look like and is not included.
