Antique Silver and Labradorite Stick Pin, Collectible. Trying to identify stone and came up with polished Labradorite and a little explanation below. The stone is cracked in the corner but is all there. I cleaned a small portion in the rear and it appears to be silver (most likely given size) or silver plate. Not magnetic, tarnished. 
Labradorite is a variety of feldspar known for its iridescent optical effects, or “now-you-see-it-now-you-don’t” flashes of color. Usually green-grey, the stone has spectral shades of blue, green, and copper. In crystal lore, Labradorite brings deep spiritual insight and connection with the other realms. It stimulates mental and intuitive gifts and acts upon the entire energy body. Labradorite is also associated with Faery trickery and portal magick. High-grade Labradorite is sometimes marketed as Spectrolite.
 
Good condition, normal vintage wear. Review all photos. I would be happy to answer any questions or provide additional photos.
