Blue Sapphire rough stone African Madagascar deep blue SMUK

Africa, the new home of sapphire. Since the discovery of deposits in Madagascar in the 1990s, the continent has become one of the world's most highly regarded sources of sapphire — known for a deep, captivating blue.

Blue Sapphire Mohs hardness 9 deep blue natural stone SMUK

Sapphire ranks at Mohs hardness 9, second only to diamond. Resistant to scratches and free of cleavage that causes cracking, it keeps its brilliance through daily wear — a gemstone strong enough to last a lifetime.

Sapphire has long been called the "Stone of Kings," adorning royal crowns and worn by the clergy. A noble blue that has been treasured across the ages.
