What Kind Of Rocks Are These?

[DLCase31238]

To me it looks like three different types of purple ones and I have no idea what the teal colored one is. I have about 100 agates I've collected over the years too

Bring them to a local gem show. Maybe some experts there can help you.

The purple one is an amethyst point.

I'd have to guess on the other ones, but the red ones look rather garnet-like.

The bluish-green one, not sure, but maybe smithsonite.

Are rhodolites and garnets completely different stones?

That was my first thought with the botryoidal (grape-like) habit. Don't know about the others.

I think , Purple = amethyst, red = garnet, green = Chrysoprase

Rhodolite is a name given to a pink to red coloured pyrope garnet, so basically a lighter coloured pyrope. They tend to be deep red.

'Garnet' is not just one mineral. There are several minerals that make up the garnet group: pyrope, almandine, spessartine, uvarovite, grossular and andradite (as well as other much rarer ones). They all have the same structure but differ in the chemical elements in their formulas. And of course, each species is given differnent variety names usually based on colour e.g. demantoid is a green gem variety of andradite.

So it's a big family!
