I went to a cave on the branch of islands called Phang ngain Thailand, these islands were hundred million years old , I went hiking on one of the islands closer to the edge of the island range and saw a cave, my family and I decided to go in , we had not seen any wildlife on the island so we were not too scared but anyway, we get in and we go pretty deep, and I shit you not, we see bones that are pre historic. We trek depper in to the cave , we make sure to watch our step because there are whales that drop 50 feet or so into the earth. We finally see light at the other end of this long maze of a cave, and right next to the exit we find this giant rock that looked like it was it was placed there, but we knew nobody had been there for years. I took a big chunk of the rock and 2 small pieces. The reason The rock is so special is because it has sparkles literally all over the rock, I dipped it in water and tried to see if it would come off but it didn’t, it Was the most dull rock but it shined like a actual diamond .
If you are interested I will show pics
