These are a few of the cool rocks I found at the rock shop located at the Broadmoor Hotel in Colorado Springs. Top left is a Tiger Iron table from Australia, 1.6 billion years old, top right is a Blue agate end table(my favorite color), middle is a fossil bed writing table, bottom left is a pyrite dollar in matrix, and finally bottom left is pyrite and quartz on a sphalerite matrix. All so cool and so expensive.
