I need help to identify this mineral rock. It is a transparent green almost light yellow in light. Surface feels rubbery or kind of waxy not sure how to describe it. It was found on farm in Lincoln County Kentucky. Thank You for any information, enclosed is some pictures.

We need to know more. Can you scratch it with your fingernail, a regular nail, another rock...does it scratch glass. Does it break easily, do you see any bubbles in the structure of the mineral. Is it brittle? Does it react with an acid,? (be careful to use safety equipment to protect your eyes and skin and to test it in a well ventilated area). Where did you find it? Like I found it near a river in Chapel Hill, North Carolina.

It looks like glass. Though as weasel stated, please provide some additional info. Also please see if you can get some better pictures of it.
