Sapphire is a precious gemstone known for its rich beauty, durability, and symbolic meaning. Here’s a clear, well-rounded description:
What it is
Sapphire is a variety of the mineral corundum (aluminum oxide). While most people associate it with a deep blue color, sapphires actually come in many colors except red (red corundum is called ruby).
Colors
- Most famous: deep royal blue
- Others: pink, yellow, green, purple, orange, and even colorless
- Rare type: “padparadscha” sapphire (a pink-orange hue)
Physical properties
- Hardness: 9 on the Mohs scale of mineral hardness (second only to diamond)
- Durability: Very tough and resistant to scratches
- Luster: Glassy (vitreous) shine
Formation
Sapphires form deep within the Earth under high pressure and temperature. They are typically found in igneous and metamorphic rocks and are mined in places like Sri Lanka, Myanmar, Madagascar, and Kashmir.
Symbolism and meaning
Sapphires have long been associated with:
- Wisdom and intelligence
- Loyalty and trust
- Royalty and divine favor
Historically, kings and clergy wore sapphires to symbolize purity and protection.
Uses
- Jewelry (rings, necklaces, earrings)
- Industrial uses (due to hardness, used in watches and electronic components)
