Amorphous silicate glass; likely copper-bearing blue slag, but possibly colored man-made glass

Aura Quartz

Titanium/Titanium-Gold treated Silicon Dioxide (SiO2)

Blue tumbled glass-like specimen; likely blue slag glass

Likely man-made glass (silicate glass), not a natural mineral; exact material cannot be confirmed from the image
