Not 100% sure: the first one I think is jasper and the second I think is white marble.

Hard to say without better pictures and more information on the pieces. Location they are from, hardnesses (different areas of the pieces may have different hardness), specific gravity, reaction to vinegar (acids).

Second one could be marble.

Both are cut and polished, and could be man made rock imitations.

I'm going with RainForest Jasper (Rhyolite) & Howlite - since Howlite is more commonly used & sold for sculpting items vs white marble.

Yes, Rainforest Jasper is the word I was trying to remember! Thanks!

On the top specimen, you may have something which includes shiny flakes of mica, muscovite ( if clear, silvery/gold) or biotite ( if black).

Confirmed Llanite, porphyritic hypabyssal rhyolite with pinkish k-feldspar and included blue quartz in felsic matrix from Llano County in Texas. Ignore Spanish pronunciation; it is called “lawn-ite”.

We need an acid test and hardness test to better ID the white wand.

I defer to your ID, very interesting.  Alot of these photos aren't very good, and I thought I saw what could be flakes of mica.
