September Birthstone: Sapphire

"A maiden born when autumn leaves
Are rustling in September's breeze,
A Sapphire on her brow should bind;
To bring her joy and peace of mind."

I've known a few couples who opted for sapphires over diamonds for their engagement rings.  Besides the beautiful color, maybe the meaning behind the sapphire is what they were trying to convey:  constancy, truth, sincerity.
