    Can anyone help identify this rock specimen? It has a wonderful royal blue color when the light catches it just right.

      I believe it is Lava ,it can cast that blue hue . Sometimes called Blue Rock . It has to do with is cooling in right conditions and no air holes in Lava . That is my guess Jono :-)

      Thank you Manikin!

      Your welcome . I was going to look for a photo for you Blue Rock Lava . I will search for one unless you already found a photo of it :-) You have such great items Jono !

      It is completely smooth with no holes and only shows the blue when held in the right light manikin. Licking it helps if you know what I mean. Lol

      LOL don't do that it could make you sick . I still think fosslized Lava which can cast a blue hue it isn't just blue all the way through or it is a meteorite :-) does it stick to a magnet ?

      Sick? Have you seen what I collect? ;)
      No on the magnet.
      It looks like a lot of thin sheets stacked on top of each other like shale.

      Labradorite would be my guess by the looks of it. A very thin layered material similar to mica, and can otherwise often appear to be a very light, drab olive-tone color until light hits it at the right angle. Most commonly, Labradorite will "light up" with brilliant shades of blue, gold, and some greens, but some specimens will come to life with a rainbow of multiple hues.
