About Cobalt Spinel Gemstones

Cobalt Spinel belongs to the spinel mineral family and crystallizes in the cubic system, giving it outstanding brilliance and light performance. Unlike ordinary blue spinel, true cobalt spinel owes its vivid color specifically to cobalt trace elements, which makes it extremely rare.

With a hardness of 8 on the Mohs scale, cobalt spinel is durable enough for daily-wear jewelry, including engagement rings. The most famous sources include Vietnam, with smaller quantities found in Sri Lanka and Tanzania. Cobalt spinel is typically untreated, which greatly enhances its value and authenticity.

Cobalt spinel symbolizes clarity, strength, and confidence, making it a powerful and prestigious gemstone choice.
