Cheat Sempervivum Gravel

Especially during quarantine, people (at least where I am, in CA) haven't really been able to get to garden centers/nurseries. This was a big deal for me when I got my first sempervivums, because they need a certain type of gravel on top of the soil in order for the leaves not to rot. How did I manage without being able to get the special gravel?

I've also used perlite for cactus and succulent mulch, but found it will wash out sometimes when watering. But another thing I've used is crushed oyster shells since I buy them anyway for my chickens from the feed store. They might even add a little calcium to the soil, too.
