It might have been around even when dinosaurs roamed the earth. Here is a craft for a rock necklace. It looks so pretty and is easy to make.
Books about rocks:
"Its a good book for beginners on this field, you wont find all of the rocks out there, but youll learn quickly about the major differences and characteristics of some rocks... It is very colorful, pictures are awesome, and I liked that the book tells you about rock and mineral uses, as well as in the ancient times as in today. I recommend it as an introductory book on the matter, then you should move to a more detailed book. I gave it 5 stars Considering that it is a pocket book." Reviewed by Jamie TO PURCHASE
