Its color comes mainly from trace elements such as cobalt, which produces an intense electric blue, and iron, which creates deeper or greyish tones. With a hardness of 8 on the Mohs scale and a clean cubic crystal structure, blue spinel is both visually striking and suitable for everyday jewelry. It is typically untreated—an important advantage compared to many sapphires—making it especially desirable to collectors and natural-gem enthusiasts. Major sources include Sri Lanka, Myanmar, Vietnam, Tanzania, and Afghanistan, with Vietnam and Myanmar producing some of the most sought-after cobalt-blue stones. Valued primarily for its color, clarity, and cut, fine-quality blue spinel can surpass sapphire in price and is appreciated for its rarity, brilliance, and ethical sourcing. Its beauty and durability have made it increasingly popular in rings, pendants, and high-end jewelry, and it is now recognized as a modern August birthstone.
