This is a polished piece of Ontario Quartz.  
 
We received a special box of amazing Ontario quartz a while back, and we've been working with them to create unique, beautiful pieces of jewelry.  Your pendant has been polished from a raw crystal right in our workshop.  Instead of taking this to a full bright polish, I stopped the process at the matte stage to give this a stunning surface.  It's smooth to the touch and feels amazing against the skin.  Turn your crystal around in the light and you will see some gorgeous rainbows on the back.  They are just incredible to look at and really dazzle in the light.  
 
I have hand-wrapped your gemstone using sterling silver wire and it measures 1.5 inches long by over 1 inch wide.  There is a nice weight to your stone.  You can see through a few parts of the crystal when you hold it up to the light - I've tried to capture that for you in the images.
 
This is an amazing crystal to wear when trying to remove negative energies and vibes from your life and replace them with healthy positive ones.
