If you were born in September, you share your birthday with one of the most storied gemstones in human history: the sapphire. Revered by kings, worshipped by priests, and worn by some of the most iconic figures in modern royalty, the sapphire engagement ring has become a symbol of enduring love, loyalty, and wisdom. When Princess Diana received a 12-carat oval blue sapphire engagement ring from Prince Charles in 1981, she set a trend that continues to this day. When Prince William proposed to Kate Middleton with that same ring nearly three decades later, a new generation fell in love with the idea that the most meaningful engagement stones aren't always diamonds.
At Felicegals, we believe every September birthday deserves a sapphire as unique as the person wearing it. That's why we offer sapphire engagement rings in a full spectrum of colors—from classic royal blue to dreamy lavender, modern teal, and earthy green—all crafted with lab-grown sapphires that deliver the same brilliance and durability as natural stones at a fraction of the cost. Whether you're shopping for a September birthstone gift or choosing your own engagement ring, this guide covers everything you need to know.

Why Sapphire Is Called the "King of Gemstones"
Sapphire's royal pedigree stretches back thousands of years. In ancient Persia, rulers believed the sky was painted blue by the reflection of a giant sapphire upon which the earth rested. Medieval European clergy wore blue sapphires to symbolize heaven and attract divine blessings. And British royalty has maintained an unbroken sapphire tradition for over a century.
But the most famous modern sapphire story belongs to Princess Diana. In 1981, she chose a striking 12-carat oval blue sapphire surrounded by 14 solitaire diamonds, set in 18-karat white gold. The ring was controversial at the time—some said it was too bold, too colorful, too different from the traditional diamond engagement ring. But Diana loved it, and the world fell in love with the idea that an engagement ring could be deeply personal.
When Prince William proposed to Kate Middleton with that exact same ring in 2010, sapphire's status as the ultimate "royal engagement stone" was cemented for a new generation. Today, colored gemstone center stones are one of the biggest trends in engagement rings, and sapphire leads the charge. In fact, sapphires are rarer than diamonds in nature—especially in vivid, saturated colors—making them both unique and precious.
What makes sapphire truly special is its versatility. While diamonds are all about brilliance and fire, sapphires offer something different: depth of color, individuality, and a story that goes far beyond the 4Cs. That's why more and more couples are choosing sapphire engagement rings as a way to say "I chose you with my whole heart."
The History of Sapphire Through the Ages
Ancient Persia (500 BC): Persian rulers believed sapphires protected their wearers from envy and harm. The stone was called "Safir" and was thought to hold spiritual power. Persian scholars wrote extensively about sapphire's ability to attract wisdom and divine favor.
Ancient Greece & Rome: Greeks wore sapphire when consulting the Oracle at Delphi, believing it enhanced mental clarity and spiritual insight. Romans associated sapphire with Apollo and wore it for protection. Roman nobles would polish their sapphire rings to a mirror shine, believing the stone could reveal truths about the future.
Medieval Europe (12th–15th century): European kings and queens wore sapphires in crowns, scepters, and rings as symbols of divine right and wisdom. Clergy wore blue sapphires to represent heaven and to ward off temptation. Warriors and knights gave sapphire gifts to their loved ones before battle, believing the stone would ensure faithfulness and bring them home safely.
Victorian Era (1837–1901): Queen Victoria's love of colored gemstones helped popularize sapphire jewelry across the British Empire. Sapphire engagement rings became fashionable among the upper classes, and the tradition spread to America.
Through every era and every culture, sapphire has meant one thing: truth. It's the stone of faithfulness, wisdom, and sacred promises—which is exactly why it's the perfect choice for an engagement ring.
Sapphire Meaning & Symbolism
The September birthstone sapphire carries three core meanings that make it uniquely suited for love and commitment:
Loyalty: Sapphire represents faithfulness and devotion. In ancient times, if a sapphire's color faded, it was believed to mean the wearer had been unfaithful. While that's not scientifically true, the symbolism stuck—sapphire became the ultimate "promise stone." This is why sapphire has been the preferred engagement stone for royalty throughout history. When you give someone a sapphire ring, you're not just giving jewelry—you're making a public declaration of your commitment to fidelity and devotion.
Wisdom: Ancient cultures believed sapphire sharpened mental clarity and spiritual insight. Buddhist traditions used sapphire for meditation. Greek philosophers wore it when teaching. It's the stone of those who think deeply and love truly. Many believe that wearing sapphire helps you make better decisions, see situations more clearly, and communicate more effectively. For a couple embarking on a lifetime together, these qualities are invaluable.
Divine Promise: Many religious traditions saw sapphire as a bridge between earthly love and heavenly blessing. In Christianity, sapphire represented the presence of God. In Hinduism, it was associated with the throat chakra and spiritual communication. In ancient Persia, sapphire was believed to be the stone upon which God's throne was resting. This spiritual significance makes sapphire engagement rings feel sacred—like your love is blessed by something greater than yourselves.
That's why a sapphire engagement ring carries deeper emotional weight than a diamond. It says: "I choose you not just with my heart, but with my mind and my soul. I promise faithfulness, wisdom, and devotion—for the rest of our lives." When you look at your sapphire ring every day, you're not just seeing a beautiful gemstone—you're seeing a reminder of the promises you made and the values you share.
Durability: Mohs 9, Perfect for Daily Wear
One of the most important questions when choosing an engagement ring is: "Can this stone handle everyday life?" Engagement rings are worn 24/7—they're knocked against countertops, submerged in dishwater, and brushed against door frames. Not every gemstone can handle that kind of wear.
Sapphire ranks 9 on the Mohs hardness scale—second only to diamond (10). That puts it well above most popular gemstones and makes it one of the most durable choices for an engagement ring.
For comparison:
- Diamond: 10 (hardest natural material)
- Moissanite: 9.25
- Sapphire: 9 (excellent for daily wear)
- Emerald: 7.5–8 (prone to chipping)
- Aquamarine: 7.5–8
- Opal: 5.5–6.5 (too soft for daily wear)
- Pearl: 2.5–4.5 (very delicate)
Sapphire's hardness means it resists scratching and abrasion from everyday contact. It won't cloud or dull over time the way softer stones do. Whether you're typing at a desk, gardening, or washing dishes, your sapphire ring will maintain its brilliance for a lifetime.
The only thing harder than sapphire is diamond—and even diamonds can chip along their cleavage planes. Sapphire doesn't have that problem. It's the rare gemstone that combines beauty, durability, and meaning in one package.
Natural vs. Lab-Grown Sapphire: Which to Choose?
This is one of the most common questions we hear at Felicegals, and it deserves a thorough answer. Natural and lab-grown sapphires share the same chemical composition (Al₂O₃), the same hardness (Mohs 9), and the same brilliance. The differences come down to origin, price, and personal values.
Natural sapphires are mined from the earth—typically from deposits in Sri Lanka, Madagascar, Myanmar, Montana, and Australia. They're often accompanied by tiny inclusions (mineral crystals, "silk" rutile needles) that tell the story of millions of years of geological formation. Natural sapphires are rarer, especially in vivid colors, and carry a premium price. They're ideal for collectors, those seeking geological history, or anyone who values the idea of a one-of-a-kind stone.
Lab-grown sapphires are created in controlled laboratory environments using the same natural processes (heat and pressure), just accelerated. The result is a sapphire that is chemically, physically, and optically identical to its natural counterpart. Lab-grown sapphires are more affordable (typically 50–80% less), more consistent in color, and more eco-friendly. They're perfect for everyday engagement rings and budget-conscious buyers who don't want to sacrifice quality.
How to Choose the Perfect September Birthstone
Choosing a sapphire engagement ring comes down to four factors: color, cut, budget, and lifestyle. Here's how to navigate each one.
1. Color by Skin Tone
The beauty of sapphire is that it comes in virtually every color. Here's how to find your most flattering shade:
- Cool skin (pink/blue undertones): Blue sapphire, lavender sapphire. Set in platinum or white gold for maximum harmony.
- Warm skin (yellow/golden undertones): Green sapphire, champagne sapphire, pink sapphire. Set in yellow gold or rose gold to enhance warmth.
- Neutral skin: Any color works! You're lucky—pick what speaks to your heart.
2. Cut by Style Preference
The cut of your sapphire determines the overall vibe of your ring:
- Oval: Classic, elongates the finger, universally flattering
- Cushion: Soft, vintage feel with rounded corners
- Pear: Elegant teardrop shape, romantic and feminine
- Hexagon: Modern, geometric, perfect for the minimalist bride
- Kite: Bold, contemporary, for the bride who wants to stand out
- Round: Timeless, maximum brilliance, traditional favorite
3. Budget Considerations
Natural sapphires typically cost $800–$5,000+ per carat depending on color and quality. Vivid blue "cornflower" sapphires from Kashmir or Sri Lanka command the highest prices, while lighter shades and less saturated colors are more affordable. Lab-grown sapphires offer the same beauty at 50–80% less, making it possible to get a larger stone or more elaborate setting within your budget.
At Felicegals, our lab sapphire engagement rings start at just $1,299 for the complete ring (stone + setting). That's significantly less than what many jewelers charge for a natural sapphire alone. This means you can allocate more of your budget to other priorities—like a honeymoon, a house down payment, or simply building your life together. Or you can use the savings to upgrade to a larger stone, a more intricate setting, or additional accent stones. The choice is yours.
Remember: the value of an engagement ring isn't measured by its price tag. It's measured by the love it represents and the commitment it symbolizes. A sapphire ring—whether natural or lab-grown—is a meaningful, beautiful choice at any price point.
4. Lifestyle & Daily Wear
If you work with your hands, play sports, or prefer low-maintenance jewelry, sapphire's Mohs 9 hardness makes it an excellent choice. It stands up to daily life without losing its sparkle. Just clean it regularly with warm soapy water and a soft brush, and your sapphire ring will look beautiful for decades.
