To want to know why my bracelet "exploded" in the middle of the night?

[MrsBennetsPoorNervesAreBack]

I have had a beaded bracelet for years... the kind with coloured beads on a kind of elasticated band. I haven't worn it for years tbh, or even touched it, but it was still hanging on a little stand which holds all of my bracelets and bangles.

In the middle of the night, I heard a small "explosion" in my bedroom. I put the light on but couldn't see anything amiss, and was sleepy so I went back to sleep without discovering the cause.

This morning, I realised that the elastic on my bracelet had snapped and the beads had "exploded into a little tray which was conveniently just under the bracelet stand. No big deal, I didn't wear it anyway.

But I'm curious to understand what caused the mini "explosion". Can anyone with a scientific brain enlighten me?!

This has zero relevance to my comment.

Mass produced, inexpensive jewellery marketed as hematite is a synthetic version called hematine or magnetic hematite, because it mimics it in appearance.

Me calling it a hematite ring doesn’t change the fact that it shattered or why OP’s bracket may have. Natural hematite is also prone to this due to it being so brittle, but it can’t be formed into rings for this reason – hence why they use a synthetic copycat. You can move on now.

Thank you for the lesson in substances, though not in manners.

Elastic can disintegrate over time and become brittle, so just snapped due to this and weight of beads.

Mr. Collins did it in a fit of pique after your daughter refused him.

Plastic disintegrates with time.
