Cobalt spinel is a rare, highly prized gemstone known for its intense, vibrant cobalt-blue color, often rivaling fine sapphires, caused by cobalt in its crystal structure. Found in places like Sri Lanka, Tanzania, and Vietnam, it's valued for its striking beauty, hardness, and rarity, with larger, clean stones being particularly sought after by collectors and jewelers. While most blue spinels get color from iron, cobalt spinel's deep hue comes specifically from cobalt, making it a unique and valuable variant.
