Blue Sapphire Meaning & Symbolism

Sapphire promotes clarity, insight, and fidelity, making it a symbol of steadfastness and wisdom. It has been worn by royalty, scholars, and the devoted across every era.

History & Origins of Blue Sapphire

Sapphire has been worn by royalty and religious leaders for more than 2,500 years. The ancient Persians believed the Earth rested on a giant sapphire whose reflection gave the sky its colour. Medieval kings wore sapphires to protect against harm and to signal wisdom, and ecclesiastical rings were often set with sapphire as a symbol of heaven and truth.

Princess Diana's — and now Catherine, Princess of Wales's — engagement ring features a Ceylon sapphire that brought modern cultural prominence to the stone. While deep blue is the most famous colour, sapphire occurs in nearly every hue except red (red corundum is classified as ruby).

Who Should Wear Blue Sapphire

Sapphire is the birthstone for September and an exceptional choice for engagement rings thanks to its hardness and rich colour depth. It suits classic and modern styles alike and is the traditional 5th and 45th wedding anniversary gemstone.

Caring for Blue Sapphire Jewellery

  • Clean with warm, soapy water and a soft brush
  • Ultrasonic and steam cleaning are generally safe for untreated sapphires
  • Extremely durable — ideal for everyday rings
  • Store separately to avoid scratching other jewellery
