Oooooh September Babies..... I envy you! Your birthstone is my most favorite color - - Sapphire Blue!!!! It's deep, it's rich, it's vibrant and regal!
I loved trying on your birthstone and I especially like the wearability of this Sandra Sing Bead Necklace:
Long ago it was believed that sapphires represented "divine favor" so they were the gemstone of choice for kings and high priests. The British Crown Jewels are filled with large, blue sapphires and of course, who could forget the sapphire engagement ring that Princess Diana received from Prince Charles? 
Your birthstone is all about Truth, Sincerity and Faithfullness - three of my favorite qualities in a person. It is strong and wearable for each and every day and rates a 9 on the Mohs hardness scale of gemstones. Being corundum, it is the second hardest gemstone we have.... rating only slightly behind diamonds.
These qualities make them perfect to set in a ring like this Thai Blue Sapphire and White Zircon Flower Ring:
Sapphires - come in many different colors too - from the most popular blue to yellow, white, green and pink/orange which is called "padparadscha". There is even a color changing variation that is very rare. The only color that sapphires do NOT come in is red... because red corundum is a ruby.

2. Judith Ripka Pave Sapphire Earrings
The depth, the saturation of color - the flash - wow! 
These exquisite gems have been prized for thousands of years. The Ancient Persians believed the earth rested on a giant sapphire and it's reflection colored the sky... what an image! 
It reminds me of this gorgeous Judith Ripka Sterling Ceylon Sapphire Ring - breath-taking!!!
You are "true blue" and gorgeous September babies .... and you deserve your high ranking on the gemstone scale.
Have a happy, healthy birthday fit for the regal beauties you are!
