Please Help Identify rocks
« on: 22/12/2014 02:31:10 »
Hello,
I received 5 minerals/rocks as a gift, i would greatly appreciate it if you guys could help identify them.
1) Bright blue-baby blue
2) Dark purple/blue
3) Bright Green
4)Black  looking, rainbow reflection.
5) hard to describe, possibly fossils?
Thank you

"Rainbow reflection" mineral possibly "Labradorite" ...

Also see labradorescence , ( no it's not the odour of a Labrador dog :).

The centre of IMG_1605 looks like a geode.

Anyone else got a idea on the other 3

Green Fluorite ? ..

It's just a guess.  Maybe get a second opinion from a forum dedicated to minerals , e.g.  http://www.mindat.org/forum.php

1605 looks like a quartz geode flanked by a couple of bits of flint.  Hardness test should confirm this.

Just a first guess; but what about sodalite for 1592?
