History and Lore
Ancient Reverence and Cultural Significance
The sapphire has been venerated since antiquity, with its name derived from the Greek word sappheiros, which originally referred to lapis lazuli. By the 16th century, the term had evolved to denote the deep blue corundum we recognize today. Ancient civilizations, including the Greeks, Romans, and Egyptians, believed sapphires had divine properties. The Greeks associated the gem with the heavens and believed it could protect from envy and harm. The Romans, in turn, used sapphires in religious ceremonies and considered them symbols of truth and divine favor.
In medieval Europe, sapphires were often used in royal regalia and were believed to promote humility and purity. The gem was thought to protect the wearer from harm and to bring clarity of thought. During the Middle Ages, sapphires were also used in the creation of stained glass, where their deep blue hue symbolized the Virgin Mary and divine wisdom.
Sapphires in Royalty and Modern Fame
Sapphires have long been associated with royalty. The gem was a favorite among European monarchs, particularly in Britain. One of the most famous sapphire jewelry pieces in history is the engagement ring given by Prince Charles to Lady Diana Spencer in 1981, featuring an 18-carat oval blue sapphire surrounded by diamonds. This ring later passed to Kate Middleton, the wife of Prince William, reinforcing the gem’s royal legacy.
The gem’s association with nobility has helped shape its cultural symbolism. Deep blue sapphires are often linked to concepts of wisdom, loyalty, and truth. These associations have persisted through the centuries, making sapphires a popular choice for engagement rings, heirloom jewelry, and ceremonial pieces.
Geological Formation and Sources
What is a Sapphire?
A sapphire is a form of the mineral corundum, which has the chemical formula Al₂O₃ (aluminum oxide). Corundum is one of the hardest minerals on Earth, ranking at 9 on the Mohs scale of hardness. While ruby (a red variety of corundum) is the most famous red gem, any corundum that is not ruby is classified as a sapphire. This includes sapphires in a wide range of colors, including pink, yellow, green, and even colorless.
The blue color of sapphires is primarily due to trace amounts of titanium and iron within the crystal structure. The intensity of the blue varies depending on the concentration of these elements. Some sapphires exhibit a color change depending on the lighting, appearing blue in daylight and more purplish under incandescent light.
Where Sapphires Are Found
Sapphires are formed under intense heat and pressure deep within the Earth’s crust, often in metamorphic rocks or igneous rock formations. The most famous sources of high-quality blue sapphires are:
- Sri Lanka: Known as the "Ceylon sapphire," this region has produced sapphires for centuries, including some of the finest blue sapphires in the world.
- 缅甸 (Myanmar): Myanmar is the source of many of the world’s most valuable sapphires, particularly from the Mogok region. These sapphires are known for their intense blue color and exceptional clarity.
- Australia: Australian sapphires are typically lighter in color but are often heat-treated to enhance their blue tones.
- Madagascar: A major source of sapphires in the 21st century, Madagascar produces sapphires in a range of colors, including blue, pink, and yellow.
- Kenya and Tanzania: These African countries have also emerged as significant sapphire-producing regions in recent decades.
Gemological Properties
Physical and Optical Characteristics
Sapphires are not only admired for their color but also for their physical and optical properties. Here are some key gemological characteristics:
- Hardness: 9 on the Mohs scale, making it second only to diamond in hardness.
- Refractive Index: 1.76–1.78
- Specific Gravity: 3.95–4.10
- Crystal System: Hexagonal
- Luster: Vitreous (glassy)
- Transparency: Transparent to translucent
- Cleavage: None (though sapphires can be brittle and prone to chipping if struck in the wrong direction)
- Color: Primarily blue, but sapphires can occur in many colors, including pink, yellow, green, and colorless.
Cutting and Enhancement
Sapphires are typically cut into brilliant or step cuts to maximize their brilliance and color. The most popular cut is the oval, which complements the gem’s natural clarity and color. Other common cuts include round, cushion, and emerald cuts.
It is important to note that many sapphires on the market today have been heat-treated to enhance their color. This process is considered standard and is not considered an imitation or enhancement. Some sapphires may also be irradiated or treated with beryllium diffusion to alter their color, though these treatments are less common and often disclosed by jewelers.

The gem was also thought to enhance spiritual insight and promote a deeper connection with the divine.
In medieval Europe, sapphires were used in religious artifacts and were associated with the Virgin Mary, symbolizing her purity and divine grace. The gem was also believed to bring clarity of thought and enhance one’s ability to make sound decisions.

Sapphire Jewelry and Contemporary Design
Sapphires in Jewelry
Sapphires are a popular choice for jewelry due to their durability and beauty. They are used in a wide range of designs, including engagement rings, earrings, pendants, and bracelets. The gem is particularly well-suited for rings, as its hardness allows it to withstand daily wear.

Lab-Grown and Ethical Sapphires
In recent years, lab-grown sapphires have become increasingly popular. These sapphires are chemically identical to their natural counterparts but are created in a controlled environment. Lab-grown sapphires offer a more affordable and ethical alternative to mined sapphires, as they do not involve the environmental and social concerns associated with traditional mining.
Many jewelers now offer lab-grown sapphire options, allowing customers to enjoy the beauty and symbolism of sapphires without the high cost or ethical dilemmas of mining.
