Carnelian druzy egg 

Carnelian is a brownish-red to orange-red mineral, a variety of chalcedony quartz, widely used in jewelry (beads, rings) and for carvings due to its durability (6.5-7 on Mohs scale). Historically known as a "Stone of Courage" and "Sunset Stone," it was used by Egyptians and Romans for amulets and seals. It symbolizes vitality, protection, and confidence.
