🔎 UNIDENTIFIED What do we have here? Geode galore! Agate? Petrified wood? What mineral looks like a fungus?

My husband found these on his business trip to Utah. Most of them are geodes, some look to be agates, but these are the ones that stand out due to their unique characteristics. I’d love to know more about them.

There’s one that looks as if there’s some kind of fungus growing on it, but my husband assures me that it’s part of the rock. There’s another one with rings that resemble petrified wood. There’s a lot of red coloring. There’s even some purplish hues. What all do I have?

Nice finds. Most of what you have is petrified wood, replaced by quartz/agate. Agate is a variety of quartz and runs a full gamut of colors and patterns.

Buncha rocks.

Purple could be amethyst or fluorite--most likely the former. I see a lot of quartz (in various forms), agatization, partial geodes, maybe some petrified wood, and some calcite.
