Sapphire: The September Birthstone

People born in September are lucky to have sapphire as their birthstone, a gem that represents wisdom, loyalty, nobility, and divine favor. According to tradition, wearing sapphire protects the wearer and their loved ones from envy and harm, bringing peace and happiness. Whether set into a ring, pendant, or a pair of earrings, sapphire makes a meaningful and enduring gift for anyone celebrating a September birthday.

Origin and History of Sapphire

The name sapphire is derived from the Latin word ‘saphirus’ and the Greek word ‘sapheiros’, both of which mean something blue. Sapphire originates from the gemstone family called corundum, which is renowned for its hardness, ranking second only to diamond. The gemstone occurs in numerous colors owing to various trace elements, though most people associate the mineral primarily with blue.

In one ancient tradition, Persians believed the earth rested on a giant sapphire, and it was this stone that gave the sky its blue color. The most coveted sapphires on earth come from the mines of Kashmir, Myanmar, Sri Lanka, and Madagascar.

The Mythology and Symbolism of Sapphire

Sapphire has, for centuries, been a symbol of truth, sincerity, and constancy. Ancient cultures cherished sapphire for its heavenly blue color, which naturally called to mind divine favor. Kings and rulers wore the gemstone believing it would protect them from harm and attract celestial blessings.

Sapphire set in an ancient royal crown symbolizing protection and nobility — Sapphires were prized by rulers for their believed protective and noble power.

In varied cultures, sapphire was regarded as protective against envy and harm. During the medieval ages, it was believed that a sapphire's color would fade if it ever came into contact with an impure or dishonest person, making it a gemstone fittingly associated with integrity.

Varied Aspects of Sapphire

Four main factors affect a sapphire's value: size, color, clarity, and cut. Of these, color typically has the greatest influence on price and desirability.

Color: The most prized sapphires display a medium to medium-dark blue, often described as "Kashmir" or "cornflower" blue. Sapphires also occur in pink, yellow, green, purple, and colorless varieties, plus the rare pink-orange "padparadscha."
Clarity: Sapphires almost always contain some natural inclusions. These are generally acceptable as long as they don't detract from the stone's transparency or brilliance.
Cut: A well-executed cut showcases the sapphire's color to its best advantage and maximizes overall beauty and brilliance.
Size: Larger, high-quality sapphires are rarer and command significantly higher prices per carat than smaller stones of comparable quality.

Physical Properties of Sapphire

Sapphire has a hardness of 9 on the Mohs scale, considered excellent for gemstone durability. This hardness, combined with its intense color, makes sapphire suitable for any type of jewelry, including rings worn daily and exposed to regular physical activity.

Some sapphires display asterism, or a "star effect," caused by tiny rutile inclusions that reflect light so intensely under certain lighting that a star pattern appears to float across the surface of the gem.

Sapphire vs. Blue Topaz: September's Two Birthstones

Sapphire is the traditional and most widely recognized birthstone for September, but blue topaz is officially recognized as its modern alternate. Many shoppers compare the two when choosing a birthstone gift, since blue topaz offers a similar color at a much lower price point. Here's how the two gems stack up:

Factor	Sapphire	Blue Topaz
Color Range	Blue, pink, yellow, green, purple, colorless, and rare padparadscha (pink-orange)	Primarily blue, ranging from pale sky blue to deep "London blue," usually enhanced through treatment
Hardness (Mohs Scale)	9 — one of the hardest natural gemstones	8 — still durable, but softer than sapphire
Typical Price	Higher; ranges from roughly $25 to well over $1,000 per carat depending on quality and origin	More affordable; typically $5 to $50 per carat
Symbolism	Wisdom, loyalty, nobility, and divine favor	Calm, clear communication, honesty, and emotional healing
Durability	Excellent; highly resistant to scratches and suited for everyday wear	Good, but more prone to chipping along its cleavage planes than sapphire

Use of Sapphire for Jewelry Design

Sapphire's durability and gorgeous color range make it incredibly versatile in jewelry design. From central focal points on engagement rings to side accents on bracelets and necklaces, sapphires add a royal touch to any piece of jewelry. The wide variety of colors also makes them perfect for styling in both vintage and modern designs.

How to Care and Clean Sapphire Jewelry

Sapphire's durability makes it relatively easy to maintain, but a few precautions help preserve its beauty. Protect sapphire jewelry from scratching, sharp blows, extreme heat, and harsh chemicals. For routine cleaning, use warm soapy water and a soft brush; for a deeper clean, professional jewelry cleaning every so often is recommended.
