What does the September birthstone, sapphire, mean?
Sapphire is the blue variety of corundum, and GIA says it has traditionally symbolized sincerity, truth, faithfulness and nobility. The name comes from the Greek sappheiros, and the stone adorned royalty and the robes of the clergy for centuries.
Ancient Persians believed the earth rested on a giant sapphire that made the sky blue, and medieval clerics wore it because it symbolized Heaven. Today sapphire also comes in pink, yellow and other colors, and the 12 carat blue gem in the engagement ring Princess Diana wore, later worn by Kate Middleton, is among the most famous.
Sapphire is a 9 on the Mohs scale, making it hard enough for daily rings, and it is the gem for the 5th and 45th wedding anniversaries. Kashmir, Myanmar and Sri Lanka are historically important sources.
What is the September birth flower?
The September birth flowers are the aster and the morning glory. Aster, from the Greek for star, stands for wisdom, faith and patience, and morning glory carries affection and the brief pleasure of a one-day bloom.
Asters bloom from late summer into early fall, so a bunch of purple and blue asters echoes sapphire's color. Morning glory is a fast-growing annual vine, and a packet of seeds with a note is an inexpensive, personal September gift.
What are the best birthday gifts for someone born in September?
September birthdays arrive with back-to-school routines and the start of fall, so useful and cozy gifts feel right: a good tote, a cardigan, a nice mug for the cooler mornings.
