Stunning Blue Luster Jelly Bean Fire Glass are diamond shaped fire glass beads that are rich with color and embrace an iridescent glaze for an unmistakable high end fire glass choice. These eye catching diamond shaped beads mimic moving water when your fire moves around on top. We recommended 2-4 inches of fire to be placed above your burner to allow amble gas to filter through the glass to give you an even flame. Enjoy Blue Luster Diamonds year round with as they become the centerpiece of your backyard or patio.
