The September birthstone is sapphire — corundum in every color except red, rated 9 on the Mohs hardness scale and the most durable colored gemstone in mainstream jewelry. With designs, this is our largest birthstone collection: rings, ring sets, pendant necklaces, and stud earrings in blue, pink, white, teal, green, and padparadscha sapphire, set in 925 sterling silver, 14K gold vermeil, black ruthenium, and solid 14K gold.
September Birthstone Jewelry Built for Daily Wear
Only diamond and moissanite sit above sapphire on the hardness scale, which means a sapphire ring keeps its crisp facet edges through decades of everyday contact — no protective setting required. The color is equally dependable: sapphire reads the same in daylight, office light, and photographs, which is why it remains the safest colored stone to buy unseen as a gift. From September birthstone engagement rings to bezel-set studs, everything on this page is built around that combination of color and permanence.
The September Birthstone Color: Cornflower to Midnight
Blue is the signature. The most prized traditional shade is cornflower blue — vivid, medium-toned, historically associated with Sri Lankan stones — but the range runs from pale sky tones to the deep royal and navy blues of Australian and Thai material. Lighter blues read quiet and elegant; deeper blues arrive with presence. Both are correct expressions of the stone, and both appear across this collection.
Blue sapphire also carries the most famous engagement-ring association in the world: the royal sapphire worn first by Princess Diana and now by the Princess of Wales, which single-handedly keeps blue the most recognizable colored center stone in bridal jewelry. Our Art Deco and halo designs draw on that same vocabulary — an oval blue center, a frame of white accents — at prices that treat the look as wearable rather than untouchable.
Beyond Blue: Pink, White, Teal, and Padparadscha
Every non-red corundum is sapphire, so September’s stone is really a spectrum. Blush and hot pinks — collected in our pink sapphire rings — carry the same Mohs 9 durability in a softer register. White sapphire is the understated diamond alternative: colorless, bright, and honest about what it is. Teal and green sapphires suit wearers who want the durability with an unexpected color, and padparadscha — the rare pink-orange named for the lotus blossom — is the collector’s shade, represented here in accessible lab-grown form.
September belongs mostly to Virgo (August 23 – September 22), with Libra beginning September 23; sapphire’s associations with clarity and sincerity map comfortably onto both. The full calendar of months, signs, and stones is in our birthstones by month guide.
Sapphire Meaning: Wisdom, Loyalty, Royalty
Sapphire has meant wisdom, sincerity, and faithfulness for as long as records exist — it appears in clerical rings and royal regalia across European history precisely because of those associations, and it remains the traditional gem of the 45th wedding anniversary. As a September birthday gift, that meaning gives the piece a second layer: not just a beautiful blue object, but a stone the recipient can explain and attach significance to.
The practical gifting advice is simple. A ring is the most personal choice and the most visible; a bezel-set pendant necklace works across the widest range of wardrobes with no ring size to guess; sapphire stud earrings are the lowest-maintenance way to wear the stone daily. All three formats appear throughout the collection in every sapphire color and metal tier, from sterling silver to solid 14K gold.
Where to Go Deeper into Sapphire
This page is the September collection — sapphire chosen for its birth-month significance. When the stone itself is the point, two dedicated collections continue the range: the full sapphire jewelry catalog across every color and product type, and sapphire engagement rings built around larger centers and bridal settings. Neighboring months live in the birthstone jewelry hub, from August’s peridot to October’s opal.
Handcrafted, Guaranteed, and Honestly Priced
Every piece is handcrafted using recycled metals and responsibly sourced stones, ships worldwide with insured delivery and a written warranty, and carries a 14-day return window on non-customized work. Complimentary engraving is available on most designs, and the custom ring service can build any sapphire color into any setting. We hold a 4.9-star average across 38,000+ reviews collected on our store and on Etsy, where we have sold since 2016. September birthstone rings here are honestly priced for what they are.
