One side looks like a typical hag stone from here. The other looks like a very thick shimmery quartz type rock. In between is maybe fossilized coral or I’m not sure. Any help appreciated.

I intended on planting deeper to bury the wooded bottom but I was in survival mode. Spines flying but it’s over. I’m calling the abundance of new blooms a thank you from the cactus.
