The name Sapphire derives from the Latin sapphirus and the Greek sappheiros, meaning blue stone. In ancient times, the term referred to several blue gems, including lapis lazuli, before being exclusively associated with the corundum mineral family. Blue sapphire is also known as Neelam in Sanskrit, Sapir in Hebrew, and Safir in Old French, all echoing its rich celestial hue. The word embodies wisdom, virtue, and divine favour across civilisations.
Composition, Physical Characteristics, and Varieties
Blue sapphire is a variety of the mineral corundum (aluminium oxide, Al₂O₃) and gains its distinctive blue colour from trace elements of iron and titanium. It ranks 9 on the Mohs hardness scale, making it one of the hardest natural gemstones after diamond.
Its colour ranges from pale cornflower blue to deep velvety midnight, with the finest stones displaying a vivid, medium to deep royal blue. The gem exhibits pleochroism, showing different shades when viewed from varying angles.
Varieties include:
- Kashmir Sapphire – prized for its cornflower-blue hue and velvety texture.
- Ceylon Sapphire (Sri Lanka) – known for lighter, vibrant blues.
- Padparadscha Sapphire – a rare pink-orange hybrid sapphire.
- Star Sapphire – features a six- or twelve-rayed star effect caused by rutile inclusions.

Blue sapphires are mined in several renowned locations worldwide, including:
- Kashmir, India – famed for legendary, silky blue stones.
- Sri Lanka (Ceylon) – a long-standing source of brilliant, clear sapphires.
- Myanmar (Burma) – produces deep royal-blue gems.
- Madagascar – now a leading modern supplier with stones of exceptional clarity.
- Thailand, Australia, and Montana (USA) – yield darker, inky varieties.
Archaeological and Significant Finds
Ancient Persian texts reference sapphire as the stone that gave the sky its colour. Sapphires adorned royal crowns and religious artefacts throughout antiquity. The earliest sapphire mines date back to Sri Lanka over 2,000 years ago.
One of the most famous examples is the Kashmir Blue Sapphire discovery in the 1880s, which supplied Europe with some of the world’s finest specimens. The Logan Sapphire, a 423-carat gem housed in the Smithsonian Institution, remains one of the largest faceted blue sapphires known.
The engagement ring of Princess Diana, later worn by Catherine, Princess of Wales, rekindled global admiration for this regal gem.

Today, blue sapphires remain coveted in fine jewellery, watches, and engagement rings. Their durability makes them ideal for daily wear, while their symbolism continues to evoke sincerity, loyalty, and faithfulness.
