September Birthstone and Flower: Sapphire, Aster & Morning Glory

September's birthstone is the sapphire, and its birth flowers are the aster (primary) and the morning glory (secondary). Together they make September one of the most meaningful months for a symbolic gift: a deep-blue sapphire set in sterling silver, paired with the star-shaped aster and the twining morning glory. Here's what each represents in tradition and folklore, and how to combine them for a September birthday.

September's Birthstone: Sapphire

Sapphire has been treasured for centuries for its rich blue colour and exceptional durability (9 on the Mohs hardness scale). As September's birthstone, it is traditionally associated with wisdom, loyalty, and truth. At Irosk, our sapphire jewellery is crafted in bright 925 sterling silver, in both Created and Natural Sapphire.

September's Primary Flower: The Aster

The aster is September's main birth flower — a star-shaped bloom (its name comes from the Greek word for "star") in shades of purple, blue, pink, and white. In tradition and folklore, the aster is associated with love, wisdom, and patience, and it was historically seen as a symbol of enduring devotion. Its cool purples and blues echo the sapphire beautifully, making the two a natural pairing for a September gift.

September's Secondary Flower: The Morning Glory

The morning glory is September's second birth flower, a climbing bloom that opens with the morning light. In folklore it has long been linked to affection and the fleeting beauty of a single day. Its trumpet-shaped flowers, often deep blue or violet, complement both the aster and the sapphire's cool tones.

Pairing Sapphire, Aster & Morning Glory

Because all three share cool blue and purple tones, they combine effortlessly for a September birthday:

• A sapphire pendant with fresh asters: A classic, symbolic gift that ties the birthstone and primary flower together.
• Sapphire stud earrings: An everyday piece that carries September's meaning without needing an occasion.
• A floral-inspired sapphire design: Our sapphire flower and petal styles echo the aster's star shape in sterling silver.
