I have two pins currently:
* The "plain" one that I chose as my pin when I first joined (which has my chapter guard and all my dangles), and
* The aquamarine (?) four points with pearls (3) in between that I won off of ebay, which I wear more now than my original badge.
I would LOVE to some day have a alternating pearl/sapphire or pearl/emerald (the sapphire because I LOVE the color blue, the emerald since it's my birthstone), but that may be way down the line after I start working on a regular basis, get married, etc, etc
No interesting pin facts that I know of
