Oh no :( I'm so sorry!

Maybe you can use a medicine pouch during the night? That would keep sharp edges from cutting you and you could still have it near you, in your energy field. I've seen some lovely medicine pouches made from seed beads. But if you prefer a different style, it should be easy to find something that suits you.

When you're awake, I'm sure you'll be able to handle it safely. It's just the nighttime when you'd have to use a little protection to avoid touching an edge.

Given the history of all tektites (formed during a truly massive impact) and the length of time that Tibetanites have been owned and handled, it might have had internal stresses that no one could have seen, or have suffered prior falls that left it vulnerable to something like this happening. Sigh.
