Thanks! But, I am sure it is noticeable.

The quick photo below has a brazilian agate on the left, and a type of granite on the right. You can see my ceiling lamp and smoke detector reflected on the mirror polish on the agate, and nothing on the granite.

Many lapidary artists will steer clear of any type of stone that does not guarantee them a high polish.
It is taboo in Rock Tumbling: I am not concerned with getting a high polish on every stone.
I really manage to get people in lapidary forums 'irate' with my philosophy.
