Cobalt spinel is a rare, naturally vivid blue magnesium-aluminum gemstone colored by trace cobalt, known for its intense, saturated hue that can range from electric blue to violet-blue, often rivaling sapphire, with origins in places like Vietnam and Tanzania, prized for its durability (7.5-8 Mohs hardness) and unique cobalt-induced coloration, though treatments are a concern for identifying natural stones.
