Fulgurite with Barite Crystal

Fulgurite with 4 Barite Crystal Pockets.
This fulgurite came from the Stoneham area in Colorado which is famous throughout the mineral world for its occurance of stunning blue Barite crystals. You can see a few of the blue Barite crystals in the picture, They don't come with it. The crystals we found closer to the fulgurites always seemed to be a darker blue for some reason?? What came first, the crystals or the Fulgurite? Was the crystal there in the ground and then the lightning created the fulgurite around it? Or was the fulgurite there already and the crystals grew inside of it at a later time?
It's a rare occurrence and we only found a few more.
