Shungite Frog

This carved frog is made from shungite, a rare carbon-rich rock found primarily in Karelia, Russia and resin. Shungite is composed mostly of carbon and is studied for its unique molecular structures, including fullerenes. Details: Material: Natural shungite and resin Appearance: Matte to glossy black surface with occasional metallic flecks Formation: Ancient carbon-rich rock, estimated to be over 2 billion years old Physical Properties: Opaque, with a density of about 1.8–2.0 g/cm³ Educational Value: Highlights carbon-based mineral structures, geological history, and the study of natural fullerenes The shungite frog combines the artistry of carving with the scientific significance of one of Earth’s most unusual carbon materials.
