Sapphire, the celebrated blue variety of corundum, is cherished for its remarkable hardness, vibrant color, and striking crystal forms. Fine mineral specimens of sapphire are found in several parts of the world, with notable examples originating from Madagascar, Pakistan, Myanmar, as well as classic deposits in Sri Lanka and other regions. The Madagascar crystals, in particular, are admired for their sharp form and brilliant fluorescence, glowing a vivid pink under ultraviolet light. Together with the bold crystals of Pakistan and the historic rubies and sapphires of Myanmar, these specimens represent the broad beauty of sapphire, making them highly sought-after additions to any collection.
