My grandfather died before I was born so not sure how or where these were obtained. At one point they were labeled. This is only a fraction of the collection, but what I am most curious about. Thought maybe 14 was Rose quartz, and 19 was tumbled Amethyst but I'm not sure. Thank you, any IDs much appreciated.

I need better pictures of 1 and 17, your spot on on your guesses 14 and 19, 7 and 12 quartz and the rest looks to be different types of agate,16 could be polished wonderstone/"rhyolite" , best I can do from the photograph.

I'll take some guesses. Like Steve said the low resolution of the image when enlarged makes seeing the detail difficult on some of them. The Agates have trade/location based names, I am only confident in a couple of those names, but they are agates.

1. Quartz crystals, cant make out what the colorful material is.
2. Agate
3. Looks like moss agate
4. Cant tell
5. Geode
6. Agate
7. Cant tell
8. Agate
9. Agate
10. Agate
11. Agate.
12. Fluorite or maybe calcite
13. Syenite rock
14. calcite, fluorite or maybe even k-feldspar
15. dont know
16. Lace agate probably mexican
17. looks like clear quartz but if its in a collection might be topaz?
18. Montana agate
19. Amethyst
20. Montana or moss agate, quartz with inclusions either way.

Consider posting more of the collection, I know agates appear to be the most interesting at first glance but if he had a large collection there could be some other interesting/valuable specimens and minerals in it.
