September Birthstone: Sapphire's Famous History

Throughout history, some prominent figures such as Helen of Troy, King Solomon, Marco Polo and Charlemagne supposedly all sported September’s birthstone. The word 'sapphire' comes from the Latin word 'sapphirus', which highlights its etymological roots and long-standing recognition in classical languages.

For a more modern celebrity, you cannot forget about Princess Diana, who wore a sapphire engagement ring that was given to her by Prince Charles. The famous ring would later be passed down to her daughter-in-law, Kate Middleton. With a deep blue sapphire at the center surrounded by diamonds and set in a white gold band, this treasure is a sight for sore eyes.

During the Middle Ages, sapphires were believed to symbolize heaven and divine favor, embodying spiritual protection and representing a connection to the divine.

Aside from the famous people who have been associated with sapphire, this gemstone has a few stars of its own. The Star of India, Star of Adam and Star of Bombay are all sapphires with a distinct star shape on them. This effect is called asterism, which is a reflection effect that seems to show two or more bands of light intersecting across the surface of a gem.

The Colors & Properties of September’s Birthstone

Sapphire Coloring

If you love sapphires but aren't drawn to the classic deep blue, you're in for a treat. While rich blue is the most iconic shade, sapphires actually come in a dazzling spectrum of colors—fiery orange, vivid lime green, bold hot pink, regal purple, and even earthy brown and smoky purplish tones. These stunning variations are all thanks to trace elements like iron, titanium, and chromium mixing into the crystal structure.

When most people hear “sapphire,” they picture the traditional blue gem. But all those other eye-catching shades? They fall under the category of color.”

The only color you won’t find in a sapphire is red—because once it turns red, it’s classified as a ruby, which shares the same mineral base but is distinct in both name and appearance.
The presence and combination of elements in the gem determine its final color. For instance, iron alone can create a purplish hue, while iron combined with chromium gives rise to a bright orange tone.

Gemologists assess sapphire colors using three key factors: hue (the basic color), tone (how light or dark it is), and saturation (the intensity or vividness). These characteristics play a big role in a sapphire’s beauty, quality, and value.

How Sapphires Are Made: Natural and Lab-Grown Gems

The journey of a sapphire begins deep within the earth, where the mineral corundum forms under intense heat and pressure. Natural sapphires are formed when aluminum oxide combines with trace elements, resulting in the vibrant colors that make these gemstones so desirable. Over millions of years, these crystals are brought to the surface, where they are discovered in alluvial deposits or mined from primary sources.

In addition to natural sapphires, today’s technology allows us to create lab-grown sapphires that are virtually identical in composition and appearance. Using advanced methods like the Verneuil process (flame fusion), the Czochralski process, and the Kyropoulos method, scientists can replicate the natural conditions that produce sapphires. These lab-created gems offer the same stunning colors and quality as their natural counterparts, making sapphire jewelry more accessible and sustainable. Whether you prefer the rarity of a natural blue sapphire or the affordability of a lab-grown stone in other colors, there’s a perfect sapphire for every jewelry lover.

Caring for Your Sapphire: Tips for Longevity and Brilliance

Sapphire jewelry is not only beautiful but also built to last, thanks to the gemstone’s impressive resistance to scratches and wear. To keep your sapphires looking stunning for years to come, a little care goes a long way.

●   Avoid exposing your sapphire rings, pendants, or earrings to extreme temperatures.
●   For regular cleaning, simply use mild soap and warm water, gently scrubbing with a soft brush to restore your sapphire’s brilliance.
●   Do not clean your sapphires with harsh chemicals, such as bleach or strong cleaning agents, as these can damage the stone or its setting.
●   Remove your jewelry before engaging in activities that might cause impact or abrasion.
●   Always store your sapphire jewelry separately from other gemstones to prevent scratches.

With these simple steps, your sapphire will remain a treasured symbol of wisdom, royalty, and love—perfect for celebrating September birthdays or gifting to loved ones on any special occasion. With proper care, your sapphire jewelry will continue to shine as a mark of elegance and enduring beauty.
