These brooches are incredibly intricate and are truly one-of-a-kind works of art.  
 
Here we have icy quartz  with a faint, faint pink hue paired off with bloody red drops for accent.  Minty leaves complete the color story.  This is not the largest of the pins but it's still a prominent focal that calls attention.  
 
These brooches/hat pins are heavy--they're made with crystal!  Sara Eileen was good enough to be sure that the attachments are equipped to handle the weight so you can affix to coats/hats (sturdy materials recommended!) without worry of not having enough support.
