History and Lore
The history of the sapphire is as deep and rich as its signature blue color. For countless centuries, this gemstone has adorned the robes of royalty and the clergy, serving as a powerful symbol of authority and spiritual connection. The elite of ancient Greece and Rome held a firm belief that blue sapphires offered protection from harm and envy, making it a favored talisman among the ruling classes. Its protective qualities were also recognized in the Middle Ages, when clerics wore sapphires to symbolize Heaven, believing the stone possessed divine properties.
Ancient Persians contributed a unique and poetic belief to the sapphire's lore. They theorized that the Earth rested upon a colossal sapphire, and it was the reflection of this celestial stone that gave the sky its brilliant blue hue. This association with the heavens further cemented the sapphire's status as a gem of spiritual insight and divine wisdom.
Beyond its protective and symbolic roles, the sapphire was also reputed to possess powerful healing abilities. Medieval Europeans believed the stone could cure ailments such as plague boils and diseases of the eye. It was also thought to serve as an effective antidote to poison, adding a practical, life-saving dimension to its perceived powers.
The journey of the sapphire to its modern status as the September birthstone is rooted in ancient traditions. The concept of birthstones is often traced back to the Breastplate of Aaron, a ceremonial garment described in the Book of Exodus, which was set with twelve different gemstones representing the twelve tribes of Israel. Later, these stones were associated with the twelve signs of the zodiac and eventually linked to the twelve months of the year. The sapphire's long-standing connection with the month of September, and specifically for those born on September 23rd, is a continuation of this ancient tradition, which was formalized in 1912 by the American National Association of Jewelers.
Geological Formation and Sources
Sapphires are formed under extraordinary geological conditions, contributing to their exceptional durability. They are a variety of the mineral corundum, an aluminum oxide (Al₂O₃). The gemstone's formation requires a specific environment: an igneous or metamorphic rock rich in aluminum but poor in silicon. The process begins deep within the Earth's crust, where extreme heat (between 200-450°C) and immense pressure cause the crystallization of aluminum and oxygen atoms into corundum. Trace elements present during this formation are responsible for the gem's color; for example, the presence of iron and titanium imparts the classic blue hue, while other elements can create yellow, pink, or green varieties.
Sapphires are mined in various locations around the world, each region producing stones with distinct characteristics.
- Myanmar (Burma): Historically one of the most celebrated sources for high-quality "Burmese" sapphires, known for their rich, velvety blue color.
- Sri Lanka (Ceylon): A major source for sapphires for over 2,000 years, Sri Lankan stones are often prized for their lighter, more brilliant blue tones.
- Kashmir: This region produced some of the most famous and valuable sapphires in the late 19th and early 20th centuries. Kashmir sapphires are renowned for their unique cornflower blue color and a velvety texture.
- Thailand: A significant commercial hub for the sapphire trade, Thailand mines and also treats sapphires from other regions.
- Australia: Known for producing darker, often inky blue sapphires, as well as the rare and valuable "parti-sapphire," which displays multiple colors in a single stone.
- United States (Montana): Montana sapphires are gaining recognition for their unique range of colors, from light blue to greenish-blue and yellow.
The famous Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone, was unearthed in Myanmar (Burma), highlighting the country's historical significance in producing world-class gems.
Gemological Properties
The sapphire is renowned not only for its beauty but also for its outstanding physical characteristics, which make it an ideal gemstone for all types of jewelry.
A Spectrum of Color
While the term "sapphire" is most commonly associated with the color blue, the September birthstone is available in a rainbow of other colors, technically known as "fancy sapphires." The only exception is red, which is classified as a ruby. The diverse color palette includes:
- Blue: The classic and most sought-after variety.
- Pink: Ranges from delicate pastel to vivid magenta.
- Yellow: From light canary to deep golden hues.
- Green: Often with a bluish-green tint.
- Padparadscha: A rare and highly prized salmon-colored sapphire.
- Colorless: Used as a diamond alternative.
Durability and Hardness
Sapphire is an exceptionally durable gemstone, making it suitable for everyday wear in rings and bracelets. On the Mohs scale of hardness, it rates a 9, second only to diamond. This extreme hardness means it is highly resistant to scratching and abrasion. However, it is important to note that sapphire has no cleavage plane, but it does have parting in two directions, which can cause it to break if struck with significant force at the right angle.

Treatments
It is common for sapphires to undergo treatments to enhance their color and clarity. The most widely accepted and ancient method is heat treatment. This process involves heating the gemstone to very high temperatures (often above 1,800°F) to intensify its blue color and improve clarity by dissolving minute silk inclusions. This treatment is stable and permanent, but it is crucial for buyers to inquire about a sapphire's treatment status, as it directly impacts the gem's value and care requirements.

The sapphire has been imbued with profound symbolic meaning throughout history, making it a powerful talisman for those born on September 23rd. The traditional associations of the September birthstone are sincerity, truth, faithfulness, and nobility.

Care and Cleaning
Given its exceptional hardness and durability, the sapphire is relatively easy to care for, but proper maintenance is essential to preserve its brilliance. The following guidelines will help ensure the longevity of sapphire jewelry:
- Cleaning: The best method for cleaning sapphire is with warm, soapy water and a soft brush. Gently scrub the back and front of the setting to remove any dirt or oil buildup. Avoid harsh chemicals, such as bleach or ammonia, as they can damage the metal settings. Ultrasonic cleaners are generally safe for untreated and heat-treated sapphires, but stones with significant fractures should not be subjected to this method.
- Storage: When not being worn, store sapphire jewelry separately from other gems to prevent scratching. A soft-lined jewelry box or a fabric pouch is ideal.
- Precautions: Although sapphire is very hard, it can still be chipped or fractured by a hard blow due to its parting properties. It is advisable to remove sapphire jewelry before engaging in activities where the stone could be struck against a hard surface.
Regular inspection of the jewelry setting is also recommended to ensure the stone remains secure in its mounting. By following these simple care instructions, a sapphire can maintain its continued brilliance and be passed down as a cherished heirloom.
