September Birthstone Jewelry
September belongs to sapphire, and we use it rough rather than faceted, so the blue arrives in uneven shards instead of a polished dome. Every stone here was picked by hand, which means no two rings or studs in this collection are the same piece twice. Sapphire sits in 24k gold over electroformed copper or in sterling silver, on 14k gold-filled (1/20) chain with a 24k dip.

What to expect from your September Birthstone Jewelry
Stones, metals, delivery windows, sizing and daily wear, gathered in one place.
What is the September birthstone?
Sapphire, the blue variety of corundum. Ours is rough, so the color reads deep indigo in some stones and nearly slate in others, in mini and five-stone rings, studs and a drop earring.
Is sapphire durable enough for a ring I never take off?
Yes. Sapphire is second only to diamond in hardness. Keep it dry and store it apart from softer stones and it will outlast the band.
A closer look at September Birthstone Jewelry
Sapphire is the traditional September stone, and it carries most of this collection: mini and five-stone rings, dainty studs, large rough studs, and a drop earring. Our sapphire is raw, so the color reads deep indigo in some stones and greyer or nearly slate in others, with visible facets that formed in the ground rather than on a wheel. Cut sapphire looks even and glassy from every angle. Raw sapphire looks like a fragment, with matte faces, small chips, and one or two spots that catch the light hard.
How to choose September birthstone jewelry
To choose, start with size and metal: mini rings and dainty studs stay quiet and stack well, while large studs and five-stone rings read as the main thing you are wearing. Sapphire is often associated with steadiness, if that framing matters to you.
What is the September birthstone?
Sapphire has been September's stone since the 1912 list, and it is September's only modern stone. It is the stone of wisdom and faithfulness, worn by medieval clergy as a symbol of heaven and by royalty as a sign of good judgment, and it is the second-hardest natural gem, which makes it one of the easiest birthstones to wear daily. Our natural stones are sorted from what the cutting trade sets aside and from vintage lots, so the rough in your piece was already out of the ground before we found it.
