What Is Blue Sapphire
About the Stone
A corundum, like ruby. Iron and titanium give it its deep, clear blue. At Mohs 9 — second only to diamond — it's reassuring for everyday wear. Long loved by royalty and clergy, it's a gem of real standing.
The Origin of Its Name
History
The name is said to come from Latin and Greek words for "blue." Its deep, noble blue became a symbol of sincerity and nobility — set in rings and crowns, and entrusted with special meaning across the ages.
About the Color, Honestly
About the Color
Much of the market's sapphire is heated to deepen the blue and raise clarity. SMUK's blue sapphire is unheated — we deliver the deep, natural blue the stone was born with. Unheated sapphire is rare on the market, with a natural colour all its own.
