Petroleum incl/ Quartz NM small loose crystals

Here's a fun offering that I love bringing to in person events like gem shows and festivals.
 
Roughly 1 gram of loose double terminated quartz crystals similar to Herkimer diamonds but that have ancient petroleum and hydrocarbons trapped inside. These inclusions have a strong reaction under UV(blacklight)
 
The crystals come in a little jar with a cork on top <3
expect 3-7 crystals per jar
