I came across this huge stone weighing almost 25 pounds. It was broken and the side showed a beautiful pattern. I did not know what it is. can anyone help me identify this rock
It actually looks more like travertine/tufa than agate! Can you place some acid on it and see if it bubbles - in which case it would clearly be travertine/tufa.
i poured acid and it fizzled for a while with tiny bubbles.
Thanks so much....
in that case its not an agate, but is confirmed as travertine/tufa. Its a very nice piece - did you find more where you found this one?
I found few more rocks in the same area. By the way, i am from Bhutan, in the Himalayas. Thanks for your advice
That looks like two different rocks. The second one almost looks like a salt compound of some kind.
It is waxy and very beautiful to look at. I liked the patterns so much and wanted to keep it in my house
