What is Sapphire?
Sapphire is a precious gemstone that is most commonly known for its blue color. However, sapphires can occur in nearly every color, with blue being the most popular. The rich, intense hues of blue sapphires are among the most prized, but sapphires also come in pink, yellow, green, purple, and even colorless varieties. Sapphires are incredibly durable, scoring a 9 on the Mohs scale of hardness, second only to diamonds. This hardness makes sapphires ideal for daily wear, which is why they are often set in engagement rings and other fine jewelry.
Varieties and Colors of Sapphires
Sapphires are available in a wide range of colors and varieties, each with its unique appeal. Here are some of the most popular sapphire types:
1. Blue Sapphire
The classic blue sapphire is what most people envision when they think of sapphires. Blue sapphires range from light blue to deep, royal blue. The most desirable blue sapphires exhibit a vivid, rich color with a slight hint of violet. These sapphires are sourced from various regions, including Sri Lanka, Myanmar, and Madagascar.
2. Pink Sapphire
Pink sapphires, while less common, have a delicate charm. They range from soft pastels to vibrant pinks. The most valuable pink sapphires have an intense pink color without being too red or purple. These stones are commonly sourced from Sri Lanka, Thailand, and Madagascar.
3. Yellow Sapphire
Yellow sapphires are found in shades ranging from pale yellow to deep golden yellow. The most prized yellow sapphires are bright and vivid, often used in fine jewelry and engagement rings. The origins of yellow sapphires include Sri Lanka, Myanmar, and Madagascar.
4. Padparadscha Sapphire
One of the rarest and most expensive types of sapphire, padparadscha sapphires have a unique blend of pink and orange. This rare color makes them highly coveted among collectors and investors. Padparadscha sapphires are primarily found in Sri Lanka and Madagascar.
5. Green Sapphire
Green sapphires, although less common than blue sapphires, are gaining popularity due to their unique hues. These stones can range from pale green to deep, forest green, and their vibrant color makes them an excellent choice for fine jewelry. The primary sources of green sapphires are Sri Lanka, Madagascar, and Montana (USA).
6. Star Sapphire
A star sapphire is a unique form of sapphire that displays a star-shaped pattern on the surface of the gemstone. This effect is caused by rutile inclusions, which reflect light in such a way that a star appears. Star sapphires can come in a variety of colors, but the most common are blue and black. These sapphires are typically found in Sri Lanka, India, and Myanmar.
Geological Origins of Sapphire
Sapphires are found in several regions around the world, each known for producing sapphires with specific characteristics. Some of the most famous sapphire sources include:
- Sri Lanka: Known for producing high-quality blue sapphires and rare padparadscha sapphires.

Physical and Chemical Properties
Sapphires are composed of aluminum oxide (Al₂O₃) and are classified as a type of corundum. The stone is transparent, and its color comes from trace elements, such as iron and titanium, which create the rich hues we see in sapphires. Here are some key properties of sapphire:
Property | Sapphire |
---|---|
Chemical Formula | Al₂O₃ (Aluminum Oxide) |
Hardness | 9 on the Mohs scale (second only to diamond) |
Refractive Index | 1.76 – 1.77 |
Specific Gravity | 3.98 – 4.06 |
Density | 3.98 – 4.06 g/cm³ |
These properties make sapphire an incredibly durable stone that is perfect for everyday wear in jewelry.
Sapphire Grading
Sapphire grading is similar to that of other gemstones, with four key factors that determine its quality and value:
1. Color
The most important factor in sapphire grading, color is graded based on hue, tone, and saturation. The finest sapphires have a vivid, pure color, with a good balance of hue and saturation. For example, blue sapphires are most prized when they are a rich, intense blue, and padparadscha sapphires are highly valued for their unique pink-orange hue.
2. Clarity
While sapphires often contain inclusions, the fewer the inclusions, the higher the quality of the stone. High-quality sapphires have minimal inclusions that are not visible to the naked eye.
3. Cut
The cut of a sapphire determines how well the stone reflects light. Popular sapphire cuts include round, oval, cushion, and emerald cuts. A well-cut sapphire will maximize its brilliance.
4. Carat Weight
The larger the sapphire, the more rare and valuable it is. However, the value also depends on other factors such as color, clarity, and cut.
