The glass holds stone inside of it. Extremely high temperatures merged the two materials. Each pendant holds a conversion between glass and stone. Some stones melt right with the glass, creating little bubbles, as they become one. Some stones create micro cracks in the glass, small screams inside. The cracks will not cause the pendants to break. Each pendant is coated in an archival sealant, protecting them for many years to come. These conversations are frozen in time.
